For this last Christmas, I purchased a Yamaha beginner keyboard (model PSR E463). The only effects that it supports are Chorus, EQ, and Reverb. It supports MIDI standards GM and XGlite and standard MIDI file (SMF) Format 0, 1 (Record).
It allows for a split keyboard, where different voices can be used. I'm used to playing SUSTAINED organ chords with my left hand, but there is no provision to directly accomplish this with the standard voices in the keyboard itself. Each voice has its own built-in ADSR envelope.
I'm new to DAWs and VSTs, but the keyboard can export audio voices in either .WAV or MIDI formats to an external device (e.g. computer).
My question is this. After I export a MIDI file (containing a voice that I want to modify), is there an affordable DAW which will allow me to modify the ADSR envelope?
At this time I just want to create a couple of modified voices where the sustain section of the envelope is set to "infinity," so the amplitude of the note is sustained fully until the key is released.
That would seemingly allow me to play sustained chords (with a modified voice) with my left hand.
I realize that you don't have this keyboard, but any general advice to my question and approach is much appreciated. TIA!
