Well, I lied. I was too impatient to switch out the jacks, not to
mention it's prudent to verify your module works before you carve it
up...
I settled for soldering a MOTM power cable on, and used alligator
clips on the input and output jacks. I didn't play with CV bank or
wave select at all yet, just swept through them with the knobs.
I like the Mini-Wave a lot. Once I got it calibrated (more later), it
had a nice clean sound. It had a lot of interesting sounding static
waves, some good sounding wave bank sweeps, the vocal formants were
pretty nice, and the quantizer bank is awesome. Sweep it up and down
with a triangle wave and vary the wave number, and you've got a fun
arpeggiator. I'll probably buy a second one as well.
OK, so to get the best performance out of this system you've got to
calibrate it. The input waveform needs to be precisely -5V to +5V to
play all the samples in any given wavetable. I found my 300s to have
slightly less amplitude than that. I trimmed the Wiard's input gain
and offset and watched the output on a scope to get a good clean sine
wave output (using a sine wave sample, natch). You could do the same
2 trims by ear, since you can easily hear when the sine distortion is
at a minimum. I also found that using my 320 was not optimal after I
had the Mini-Wave calibrated to the 300s, which were pretty
consistant with each other. So I may look into some precision
resistors around the 300 VCO and 320 LFO waveshaper circuits, to get
exactly 10V peak to peak outputs for all modules which might drive a
Mini-Wave.
All for now,
Moe
