Dear Victor, I thought alwyason would be necessery to activate the instrument. But why does it prohibit the instrument to produce sound?2016-03-20 19:36 GMT+01:00 Victor Lazzarini <Victor.Lazzarini@nuim.ie>:

The instr is activated by midi, alwayson is not needed, but the issue might be elsewhere. Victor Lazzarini Dean of Arts, Celtic Studies, and Philosophy Maynooth University Ireland

As Victor hints, removing the alwayson will allow your instrument to work. MIDI notes will activate your instrument when needed so no other activation is necessary. It used to be that we needed to have some sort of dummy score event to prevent Csound from exiting, when it assumed performance had completed, but we don't even need to do that anymore. Your alwayson on was starting a held note within which iton (pluck frequency) was zero (not a midi note so cpsmidi output is zero). This was causing a large DC offset that was preventing the audio from subsequent MIDI activated notes from begin representable in Csound's output signal. Hope this helps Iain.
