Picked up my first modules, Branches and Tides, I seem to be having compatibility issue running SQ-1 into Branches and then triggering MS-20 Mini envelopes 1 and 2.
Output B from Branches appears to trigger Env 1 as expected but output A triggers both Env 1 & 2.
Is this due to S Trig and V Trig? I read somewhere that someone had similar issues with Grids.
Also, Tides output is normalled to +7v, I want to control the level with a +5v envelope from MS-20 Mini, however, the level doesn’t get back down to silence. Do I need to get something to scale or offset my envelope voltage up or down?
That’s weird because there’s no different in Branches’ output circuit for outputs A and B. Have you tried increasing the gate length on the SQ-1? That was the problem with Grids.
As for Tides’ level, it might be that the MS-20 mini envelope doesn’t exactly go back to 0.000V at rest (you can check that with a multimeter). Or that your Tides is not calibrated correctly (have you done anything related to calibration/alternative firmware with it?).
Thanks for your reply. Tried increasing gate length / duty cycle on SQ-1, Branches still behaves oddly when probability set more to A. It’s like Env 1, triggered by output B doesn’t close, yet when I trigger the same Env from a gate source not connected to Branches (second gate on SQ-1), Env 1 closes as expected.
Haven’t changes anything on Tides. It might be a calibration issues as I’ve just tried controlling the level with two different LFO sources and the same thing happens. The level drops significantly but is still audible. Should I look at re-calibrating?
Does the same problem occur when you use the second channel of Branches?
Depends… Some LFOs and envelopes have badly designed output stages that do not exactly rest at 0. In such cases, you really need an offset to lower their rest level to 0V exactly. So I’d check first with a multimeter that the problem does not come from the LFO / envelope. If this is the case, the calibration procedure won’t solve anything.
Do you have any documentation/specifications explaining what kind of signals these inputs expect?
Only what I can see in the manual that they take trigger inputs, negative polarity which I believe is S-Trig on MS-20 Mini.
Does it appear to work when you swap what is connected to Branches’ outputs A and B?
If I swap the output around (Out A to EG1 and Out B to Trig In I get the similar results, EG 1 not behaving as expected, staying open too long. If I stop the sequence with EG1 open it won’t close at all. I have not experienced this when using SQ-1, only when using Branches.
Did you try to put some other module in between? For example if you have a spare sequencer with a trigger/gate out, you could trigger that with Branches and use the trigger out from the sequencer to trigger the MS-20. That could help in rule out some possible causes.
Hi Papernoise, thank you, great idea, will investigate. Bit short on modules at the moment, was wondering if routing through the ESP on MS-20 might help. I’ll try it out. Might be looking at getting Streams, should play quite nicely together I think
