You can't alter the length of the output buffer, you have to produce as many samples as you consume. For a simple gate, you should be copying samples from input to output when its open and writing 0.0f's to the output when its closed. I used a simple state machine with 4 states: closed, opening, open, closing. c.f. http://plugin.org.uk/src/gate_1410.xml The envelope function is a linear segment: g^ ___________ a| / \ i| / \ n| / \ _______/ \_________ time--> closed open open clos closed ing ing Which is obviously wrong, but I haven't to round to fixing it. Applying a low order, low cutoff lp filter should be enough. - Steve
