It essentially acts as an inverting amplifier with an amplification of over 50x. One could replace R19/R20 with smaller values to red...

fh-1 and fhx-8cv

Hi, I've been using an FH-1 without issue for a while and decided to get the expander, FHX-8CV, which I believe is a supported setup. I have the expander hooked to power, and the expansion cable is connected from GT2 on the FH-1 to the GT1 expansion IN on the FHX8CV, when I boot it just sits for a m...

Im comfortable with some level of modding but unless its straightforward im cool with stock design of course. The demos I've heard sound good to my ears :bananagui...

The mod works in all Syncussions (inclusive sy-1m) and replace the tl497. The diode in the THC version is useless because with the diode mod you get Lfo problems (and the fix of that symptom to change resistors do not help) Can you describe the symptoms of the LFO problems from the diode mod?

Does anyone know of or provide a service that clones small plastic synth parts using 3d printers? I was helping a friend add a highly liquid midi kit to a yamaha cs01 mkII and lost all the switch caps.
