Futureman Posted September 17, 2008 Report Share Posted September 17, 2008 Is this possible to implement software wise?I've got a few bits of kit that use the "Short to ground" method to trigger a note (Early Yamaha & Korg Stuff etc)It would be cool to be able to change the polarity of the gate out, ie... normally it's low, but when a gate is sent out, the signal goes high.... On Early Korg gear, the signal is normally high, but during a gate, the signal goes low.. (A short to ground)I'm not 100% sure that this can be done via software, but if so it would be ideal..Failing that, I might slap a few of these (V-trig to S-Trig converters) inside my sequencer..RegardsMike Quote Link to comment Share on other sites More sharing options...
stryd_one Posted September 17, 2008 Report Share Posted September 17, 2008 The CV/gate code reads a byte from memory and sends it to the appropriate pins... If you find the code that handles that byte, then you can use a comf instruction to flip the bits before they are sent to the appropriate output. I'd start with seq_ext.inc ;) Quote Link to comment Share on other sites More sharing options...
TK. Posted September 17, 2008 Report Share Posted September 17, 2008 Yes, see http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fsequencers%2Fmidibox_seq_v3%2Fsrc%2Fseq_ext.incE.g.:#if DEFAULT_ENABLE_J5_GATES movf GATES, W, BANKED xorlw 0xff call J5_IO_Set#endif[/code] will invert all pins [code]#if DEFAULT_ENABLE_J5_GATES movf GATES, W, BANKED xorlw 0x01 call J5_IO_Set#endifwill only invert the first pinBest Regards, Thorsten.

Futureman Posted September 18, 2008 Author Report Share Posted September 18, 2008 Cool, I actually understand that.. brings me back to my 6502 ASM days..Could this possibly be implemented as a menu option in further software updates?
