Whats up with the Sustain Level of Envelope 1?
A Due to an error in the Matrix-1000 firmware this particular parameter cannot be set by Midi. I’ve tried to kludge this by selecting any of the 800 preset patches with a similar Env. 1 Sustain Level and then sending all the other parameters. But a quick inventory of the presets revealed this strategy would leave far too many gaps to be satisfactory so im afraid we’ll have to live with this. Thankfully there are two other Envelope Generators available and they are not crippled by this peculiar bug.
