cosmosuave Posted July 6, 2014 Report Share Posted July 6, 2014 First off I know there are a lot of variables at play here and this is the first time I have encountered an issue trying to trigger a synth via midi.. I am unable to to trigger the S1000 as it is set for for channel 1 and I have defined MIDI port out#2 on SEQV4... The S1000 works fine when I trigger with a M-audio Oxygen keyboard set on channel 1... Not sure what gives... The SEQV4 will trigger my MBSID no problem as well as my MKS-30... Maybe someone here has had the same issue with the S1000... There is some setting I am missing... Thanks... Brian... Quote Link to comment Share on other sites More sharing options...
Imp Posted July 8, 2014 Report Share Posted July 8, 2014 I once had a problem to trigger an old doepfer Midi-to-CV module with the SEQ4L. On the page for the LPC17 TK wrote: "this limitation especially hurts for the MIDI OUTs, which can't be supplied at the (commonly used) 5V anymore. As a counter measure, R21, R22, R26 and R27 resistors are 47 Ohm instead of 220 Ohm to achieve a current of more than 5 mA for driving the optocoupler of the MIDI target device." If that is causing the trouble, a buffer or levelshifter might help. You could also relay the midi connection through your computer as a quick workaround.

cosmosuave Posted July 8, 2014 Author Report Share Posted July 8, 2014 (edited) I just noticed the Quad IIc module that I have installed has 220 ohm resistors I will try the outs on it as I was using the outs on the LPC17...

cosmosuave Posted July 8, 2014 Author Report Share Posted July 8, 2014 Thx will look into replacing those... Quote Link to comment Share on other sites More sharing options...
lukas412 Posted July 8, 2014 Report Share Posted July 8, 2014 This probably doesn't specifically help you, but I have been using my seq with an s3200xl and an s5000 with out any issues. I assume the s1000 is very similar so shouldnt need any special treatment. Luke Quote Link to comment Share on other sites More sharing options...
