I tried to input a 1/4 jack into the gate, but it did not help. I think it must be 5V to work.Nig wrote: If you plug a jack into the gate input on the back of the Minitaur is will keep the gate open so you don't need to keep triggering it, a 1/8 inch jack to a 1/4 inch jack adapter works best here but a cable with a 1/4 inch jack will do the trick too. Just make sure nothing is connected at the other end.
This is a physical limitation of the synth, probably to do with keeping the very low notes more stable. I'd reckon if you open the gate like above it will bypass this limitation for inputed audio.
I finally succeeded in using Minitaur as an analog filter for Messiah. I reduced output a lot, seems like the Minitaur's input will distort very easily. (And that is ok with me, it is a useful feature.). Then I got clean audio. I set the souncard's output to max, and amplified the cutoff by 1.8, then I had strong enough cutoff, and I offset the Minitaur hardware cutoff at 10 o clock (Ca. 30%) , and then everything sounded as expected.
The Messiah filter mode is set to "ignore program change", and there is a built in bypass mode, and it was easy to route all audio to right output, so there is no problems on the softsynth side of things.
All the best
