Bassline synth woes

MIDIbox SID
1

Hi…

I keep having trouble understanding how to get the bassline synth working properly… all I’d like to do it get it to play the same bassline on both instruments, just so it’s a bit stereo… but this seems to be beyond me a bit. 
Or at least… I’m trying to use the knobs to control the filter, and for some reason it only controls one of the instruments… it’s very confusing as it happens even if I go in and change the assignment to “filter L+R”

and it happens with multiple SID pairs, all of which have filters that work fine for other patches…
Anyone got a guess as to where I am going wrong?

thanks!

I’m not exactly sure, but I think it’s because of the Midi Channel. Bassline sends at M Channel 1 so you change the SID at Core 2/3/4 to Channel 1. 

I can’t test it by myself atm.

thanks, I thought I had done this, but will have another look to see if I have done it wrong somehow…
I thought it was the L&R SIDS of core 1 I needed to assign the same channel. They seem to play the same pattern fine, I just can’t seem to control the filter (or decay, or accent) from the knobs for one channel.
