- Q: What is SoundBridge ?
A: Sound Bridge is a utility program, that compiles custom samples from a variety of sources into the QuadraSynth Voice format, and then downloads those Voices to an Alesis - compatible PCMCIA Sound Card via MIDI SysEx to a QS6, QS7, QS8, QuadraSynth Plus Piano or S4 Plus.
- Q: Where can I get it , and how much does it cost ?
A: . SoundBridge is freely downloadable from : The QS Software Page
- Q:What else do I need ?
A: . All you need is a QuadraSynth or QS synthesizer along with a standard MIDI interface. If your synthesizer has the onboard serial interface, just connect a serial cable from your synthesizer to an available serial port on your PC (make sure you have the Alesis Serial Port Windows MIDI Driver installed). You will also need a PCMCIA Flash RAM or SRAM card. Check the QuadraCards Page for details.
Sound Bridge does NOT require additional hardware. The files are loaded directly into Sound Bridge from any disk (CD-ROM, floppy disk, hard disk, etc.). Sound Bridge will, however, allow the user to audition samples from the disk through most PC Sound Cards.
- Q:Is my original QuadraSynth / S4 upgradable for SoundBridge ?
A: . The PLUS upgrade kit is no longer available, so the only way to become a QS Plus Piano or S4 Plus owner, is to sell the
old QS or S4, and buy a Plus. It's not as bad as it looks, you'll be able to "upgrade" this way, for about the same cost, since the price difference
between the original and the Plus is no more than the cost of the upgrade.
If you want to keep the old QS, you can still have some use for SoundBridge, you just need someone with a Plus to load the samples for you.
The original Quadrasynth WILL read sample and program data from a compiled Sound Card, but it will NOT compile a card via MIDI nor will it
recognize sequence data on a card.
- Q:I own a QS6, can I play MIDI files from my card ?
A: . Yes, you can play MIDI files, if you have upgraded your QS6 to Softvare Version 2.0.
Version 2.00 software is available as an EPROM upgrade kit. This kit is user-installable and comes with all the necessary instructions and tools. The only other tool you will need is a Phillips type screwdriver. The upgrade is available free of charge to registered users who have purchased
their units after July 1, 1996. A proof of sale is required to receive this upgrade free of charge. Otherwise, this EPROM upgrade is an enhancement
to the original QS6 operating system. All previous QS6 owners must purchase the upgrade through our Parts department at the cost of $39.99
(Plus any applicable sales tax and shipping charges).
- Q: What type of sample files can I use ?
A: . From the Project Manager, Sound Bridge can load two types of sample files:
These are the two types SoundBridge can complie to your card. You are not limited by this, if you use sample converter utilities.
There are very handy programs available, for converting all kinds of samples to the format SoundBridge needs. The possibilities are endless...
- Microsoft PCM Type Wave files (*.wav)
- Raw PCM Sample Data (*.pcm; *.*)
- Q: Can multisamples be loaded into flash cards?
A: . Alesis has plans to add key-mapping of samples to a future version of
SoundBridge. In the meantime, the Mac version of SoundBridge accepts
SampleCell Instrument files, which are collections of AIFF or .WAV files
with key and velocity mapping. One PC user has reported successfully
loading these by running the Mac SoundBridge v1.0 under “Executor
2.0/DOS” Mac emulation software.
- Q: Is there a way to create SampleCell Instrument files without owning
A: . There is, but it is not for the faint-of-heart. Existing SC Instrument
files will play any collection of AIFF samples that have the same names
as those originally intended for use with the Instrument. By cracking
into the Instrument file and changing the text strings (this can be done
on a Mac in ResEdit with an extension called “Forker”), one can make any
number of multisamples from a single SampleCell “template”. The samples
must have the same original pitch as those they replace, and the names
must have the same number of characters.
AWave, a PC shareware program,
can create SampleCell instrument
files, but these are not readable by SoundBridge. They will, however,
open in Digidesign’s SampleCell editor, where they can be saved as bona
fide SampleCell files which SoundBridge can open.
- Q: Where can I find (preferably free) samples ?
A: . There are some valuable resources on the Net, you can find many free,
shareware and demo samples, and also places that sell sample CD-s and CD-ROMs.
CD-s are less expensive, but they contain only raw audio data, and you will have to create loops, which is not as easy as some think.
CD-ROMs cost more, but the samples are already looped, and can be used without too much effort. Most companies offer free demo,
so you can try some of the sounds before buying the full CD.
- Q:Are there any useful utilities downloadable from the Net ?
A: . Yes, there are several digital audio editing and sample converter utilities out there, you'll find a list below
with many shareware and commercial demo programs to choose from.
- Q: How to deal with sysex files ?
A: . Many QS users reported problems with transferring sysex banks to the card. I checked it myself, and noticed,
that the sysex bank must be located in the SoundBridge directory, to be succesfully transferred. The bank must to be in
standard sysex format, (propietary formats of some editors can not be used) Check the file size, if it's 79,479 bytes, then it's probably
a full bank in the correct format. If you use editors, and they don't save the banks in sysex format, you should dump the bank to
the QS (save first the current user bank) and send it back using either Cakewalk, or Freeloader to get them in the
correct format, and save them into the SoundBridge directory.
Don't forget, you can load only one sysex bank to a card. If you want to use your card for storing program and mix data only, use the
synth to transfer the banks from the user bank, one by one. In this case you don't need SoundBridge. The Alesis 256kb RAM card is
better to be used for this, since it can't hold more than a few seconds of samples, but able to store four full banks of mix and program data.
- Q:Once I loaded my samples to the card, how can I find, and play them ?
A: . Press the Program button, to enter program mode, then press the EDIT button, and go to ASSIGN VOICE. You will find your samples
in the new Sound Groups. Drum samples can be found if you first enter DRUM MODE, and then scroll thru the Drum Sample Groups.
To audition your samples, you have to assign them to a program. It's a good idea to reinitialize the synth, (and the program buffer with it) so you
can start with a blank program. You may also download an entire bank of initialized patches from the Sounds Page
It's very handy, if you want to write a lot of new programs.
- Q: How can I learn to write programs ?
A: . It's easy, just do it. : -).The best way to find out how programming is done, is to look
inside different programs, see what methods the programmer used to enhance the raw sample. Try to adjust different parameters, and check what
effect they have on the program. Use an Editor Program, so you will be able to edit on the big screen and get a better idea, what programming
options you have. Spend some time experimenting before you give up, and (I hate to say this) read the manual...
Take advantage of the free Programming Tutorial, that you'll get, when you purchase the QE Plus Editor/Librarian.
- Q: What should I use to write MIDI files ?
A: . MIDI files must be in Standard MID File format, to use them with your QS6, QS7 and QS8. Any sequencer, that can save
files in this format will do. You can NOT use .WRK or .SNG files for example, but .MID files are fine.
Tips and Tricks
This section is reserved for your suggestions, please send your tips and tricks to me, so I can post them here.
Mac users are especially encouraged to contribute any useful QS-related information. I use a PC, so I can't test or recommend any software, and can't give any computer specific advice to Mac users.
Your comments, suggestions, contributions to this page will be appreciated.
- Keep those samples as hot as possible without distortion. If your
wav editor offers compression it might be useful to maximize gain.
- Sound forge works well for preparing samples and loops. Editing
loops in SB is really not possible, unless you don't mind clicks and
- I find it works well to do all the looping in my sampler, use Forge
to get it, then bridge to send it to the qs8.
- Many inexperienced folks are bound to be a bit disappointed when they
hear there first run of samples. It takes a bit of work to get it
right. The samples must be clean, loud, and looped well.
You simply have to have something that can do loops right, be it Sound
Forge, Alchemy, or a decent PD Wav editor. You can find them in the
Utilities Section below.
- You should normalize the gain and perhaps even boost it a bit more if you can. (Hint, on some
sounds, digital clipping sounds good). All those ROM samples in the QSx were meticulously tweaked to get the best response. Yours will pale in comparision unless you meticulously tweak them to make them as hot and
full bodied as possible. Remember! You can always dull a sample in the QS with its filter, but you can't add upper harmonics that are not there to begin with. Its OK to send them in a tad bright.
- The biggest problem you will face is a sample with poorly omptimized gain and a lack of
upper harmonics. Those tend to be nearly useless. It is wise to patch an eq as you sample.
Make those suckers HOT!
- There is Alot you can do with a properly looped, bright sample, far more than you can do in most
samplers. Stack it up X4, assign a different effect to each sound, combine them, pan 'em, detune them, morph them with the tranform generator, use those 12 lfos and envelopes. And don't forget the
sliders/quad knobs, velocity and pressure controls. The bottom line is, if you want excellent results, you have to do the work. If you don't want to do the work, get some of the new ROM cards, where the work is done for you.
- I would not be shy about sending sounds at 22050 sampling rate. there are actually benefits to doing so.
Save 44.1 for samples that really need it, cymbals, bells, anything that needs precise high end. 90% of things I
want to play don't need it. Some techno stuff sounds better at a lower rate. Orchestral stuff and acoustic instruments do benefit from 44.1. Synths are a wash.
- Memory goes farther
- You get extended keyboard range.
From Wynne Hexamer :
- It appears that when you first construct a project file that Soundbridge
records the lengths of the samples. If you happen to edit one of the
samples (and change the length in the process) and then attempt to
compile the project to the flash card, it stops downloading at the file
in question with the message "error loading file". The work-around I
use in such cases is to construct a new project of the same files in the
process recording the new file length.

Programming Basics No. 1: Using Copy Functions to Create Complex Programs
Especially for new Quadrasynth Programmers
Lets say you want to go beyond tweaking factory patches and doing simple
stuff like changing the instruments, octave etc., and want to develop voices
all your own.
1. To start, set up a default patch with preferences
you nearly always use so you don't have to start from scratch each time.
On the QS, I use the following defaults, which are followed by many of
the factory patches.
- FX level is set to a level where you can hear it, but its not in the
- Controller A is routed to Filter Cutoff so the sound fades out as you
move the slider up.
- Controller B is routed to change an FX parameter. Delay 1 level works
- Controller C is routed to amp envelopes--greater release time is a
- Controller D is routed to boost the FX send about 50
- Pitch LFO is set to a reasonable level at a speed of 47 and is routed
to the mod wheel. AMP and Filter LFOs at level zero at a speed of 47. (if
you are doing techno sounds, set all the above to 57)
- Aftertouch is set at a subtle level.
- FX config is set to your favorite. Mine is the 2 bus with EQ.
Copy this default program to every location in an empty bank. Of course
you change these as you get into editing the patch. You only need to do
it for sound 1 as before you get too far you need to learn...
2. Copy functions. You'll grow old or mad or both
if you don't learn to copy sound layers, either in your ed lib or on the
Qs front panel. On the QS machines, press STORE then PAGE to get to the
copy menu. In Unisyn, COPY the patch to the clipboard, then use the PASTE
SECTIONS function on the menu.
3. Instant Gratification for the New Programmer: A little
I will assume you understand what envelopes, LFOs and other basics are.
If not, check the manual that came with your synth.
Did I mention I am available for programming projects? Email
a. Tweak Sound 1 (whatever sample you find most interesting at the moment).
Get the envelopes right. Get the FX right. Get the velocity right. Set
the controllers/modulators. Don't forget lfos and AT. Keep in mind anything
you neglect to tweak now will have to be done times two or times four after
b. Now copy Sound 1 to sound 2
c. Pan sound 1 left and sound 2 right, detune them a few ticks. You
now have a giant “stereo-ized” image.
d. Now make a few micro-edits to sound 2's envelopes and filter. You
might be surprised how just a few differences between the sounds can add
depth and dynamism to the sound when you have the L/R thing going. So you
got it sounding real cool. Well wait, we're not done yet.
e. Copy sound 1 to sound 3 and 2 to 4.
f. Mute Sounds 1 and 2
g. Choose similar instrument samples (i.e a different
horn, string, drum kit and use the same on for both sound 3 and 4. It probably
already sounds pretty good, as its panned, detuned, envelopes are tweaked,
etc. Do whatever adjustments you have to. So now you have two patches in
one program--now we have to blend them. Here's the easy way.
h. On sounds 3 and 4 go to the filter and give it a negative setting
so you cant hear it--that's right till you hear nothing. (Remember sounds
1 and 2 are still muted so you can't hear them either.) Now go to Controller
A which is already assigned to filter cutoff but give it a positive value
to when you move the fader up, the sounds 3 and 4 become audible.
i. Unmute sounds 1 and 2. Controller A should fade smoothly from sound
1/2 to 3/4. If it isn't smooth go back and make adjustments to the filter
cutoff amounts--you should be relatively close.
j. Now go back over the program and add things that will really make
this patch a standout.
So now you have made your first complex program. Using the copy functions
made this quite painless. You will probably start wondering, "hmm...
wonder what it would sound like if I used 4 wildly different instruments
in this program". Welcome to programming, friend. There are many paths
that may open in your imagination at this point. Every road you take will
open up a dozen more roads.
Note on the QS machine you can also Copy FX. In Unisyn's Paste sections,
you have even more flexibility. You can copy envelopes, lfos, modulators,
nearly any parameter, from sound to sound. This is an extremely powerful
tool--check it out.
Where do you stop is the better question. You stop when you are having
a tremendously great time with your new creation and can't think of anyway
to improve it. For me, the keyboard starts feeling "different"
when I have a solid program. The hands, without any thought on my part,
find things to do with the sound. Go and explore. Its quite a boundless
sonic world in a synth as well endowed with samples as the QS machines.
As you get into programming, you realize there are really no rules, just
habits. (Some philosophers say that its habits that keep our world orderly,
not rules and laws.)
Good Work Habits for Programmers.
1. Naming and renaming programs. When I am experimenting I always assign
a name with a lower case first letter and I add a number at the end of
every significant crossroad, so the name will be something like "sonic
hell1" or whatever. That way you can always go back in case you really
screw things up. As the patch nears completion, it might be named closer
to the final name, perhaps Sonic Well9. When the patch is done, I delete
the number, so I know anything without a number is the final, definitive,
2. Do I need to tell you to save your bank often and send the bank to
the synth at regular intervals? Nah, you know that, and you know what happens
when your computer crashes or synth crashes, or both crash at the same
3. Think of practical matters as you program. You create a patch in
order to use it in a composition. Keep your sequencer fired up as you make
patches and use them in a test sequence. Is the level right? Does the velocity
and AT work as it should? Is it named so you will remember what the sound
is when you see it in a list of 127 other sounds.
Of course there are more. I hope this helps a few of you get into the
joys of sound creation.
No one in the world can make THE sounds for your unique musical statement
like you can.
Stay tuned for the next installment!
