I did some measuring and spice simulating and think this is probably caused by the circuitry around IC1A/IC2B which is extremely sensitive to fluctuations in ground. It essentially acts as an inverting amplifier with an amplification of over 50x. One could replace R19/R20 with smaller values to red...

please count me in, very interested!!!

SUBSCRIBED

yep that was it. works great!

I assumed that the flashing red lights meant it wouldnt work and didnt even progress into testing further.

I will see if it just works despite this and follow up, thanks!!!

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...

syncussion and sds3 are the holy grail drum synths! wooo! killin it psyco x!

nice!

Im totally fine either way, was just curious and hopeful that these reissue filter chips could be swapped with maybe some minor changes. 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...

interesting - anyone want to speculate on the likelihood/complexity of 2040 adaption?

thanks that helps!

any ballparks on the cost of the bom/enclosure?

I'll post the modification details soon.

uh thats awesome! i'll be placing an order then any chance these mods will also allow the utility box to work with rev1?

finally discovered this module and am building one, but have a small issue sourcing 400kohm 0805 resistors. Im finding 397k and 402k. Does it matter?

super cool, do want!

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? I thi...

so the fix i implemented on rev1 is seemingly recreating a problem that was introduced on rev2, that this fix addresses in addition to the power noise elimination? interesting.. well if i can provide any more info to Patrick or you for advice please let me know! its awesome having this thing without...

cool, great to hear i didnt do something wrong. standing by for more advice!

well.. something is a little weird with the power mod after all :\ i will try to upload a video but basically if mine is off now for a little while, when i first power it up the lfo/pitch escalates until it sounds locked up and doesnt make any sound. it starts to work properly after about 2-3 power ...

finally had a moment to install this last night, works perfectly. THANK YOU THANK YOU!

finished my core/mod build finally, sounds ACE!!! no issues still havent calibrated but love the way it sounds as-is

i love a good kit and im excited to see other recommendations here to explore. i have to recommend music thing radio, music thing turing, and music thing pulses expander for a lot of weird fun straight away. ive ordered these kits from thonk and never had issues with their product. the kits are well...

thanks for the suggestions everyone, i'll look into what those services have to offer, seems like some good options out there.

anyone know if any of the other yamaha pss type synths use the same kind of slider caps?

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. This is the more rare black version of the synth so it seems more difficult than usual to even buy...

Amazing! YES!

Ordered!
