A close up look at the Roland SH-101
Here's a close up look at the Roland SH-101, it's features and how to program it's internal sequencer. I also show how I use it with my Roland TR-606 and Doepfer A100 modular synthesizer.
How do you adjust the rate? I want it to go into the audio range, or as close to it as i can get. Yours seems to get there. Of course i could just MOD it =o]
i dont think you can adjust it directly (only LFO modulation offset for the bender board), best bet is to do teh full calibration, startign with the D/A adjustments, it might help. Its all in the service manual. If theres still differences its probably down to component tollerance.
Your LFO rate seems to go higher than mine.
ReplyDeletemaybe one of them needs adjusting, its been a whle since i did mine.

ReplyDeleteApparently, bridging R8 seems to yield good results.

ReplyDeleteLooks like the mod for the 101 is a bit different.
ReplyDeletei miss mine, i sold it years ago for £150 when i was super skint (i only paid £80 for it).
ReplyDeleteGreat little synth.
Just modded mine for audio rate modulations. Works like a charm!
