sticky notes

Hi all,

i've just managed to install a sid2sid unit in a old breadbox c64 and using the latest mssiah cart and everything is running ok (touch wood); however, when i play the c64 using a midi keyboard i get the problem that the cart or software in the cart doesn't always receive the midi off command when i release the key, resulting in sustained notes. this happens when i press more than one key at a time, which is a real problem when playing chords in multi timbal mode.

Any suggestions to solve this problem?


Thanks

Hi there Andrew/plainlazy,

First of all, try another MIDI cable and see if that works better.

Edit: Just seen your other post here: http://www.mssiah-forum.com/viewtopic.php?id=1733

Seems it happens with the diagnostics page too, so ignore my advice about MIDI cables.

Re: sticky notes

yo, believe it of not part of the sticking note problem has been reduced by changing my midi controller. before i was using my roland jx-305 synth, which funny enough there's another post on here with someone having problems sticking notes when using their roland v-synth; so it must be how roland deals with midi data. as for the very quite sustained osc tones notes that's still present, so i guess it's something to do with how the sids are installed.

to give an idea, even when the note is removed the sound dies down to a very quite volume, modulation still contines to modulate the osc or filters????


cheers

Re: sticky notes

Naeh, the oscillators of the SID chip are not closed to 100%, that's why you got the quiet tone even when the note is stopped.

The same 'issue' is present in the Sidstation for example..

Best way to cure that is to use a noise gate.
