Hrm back when I had real hardware in spades I spent most of my time programming and not enough composing. Learned my lesson.
But I am a long standing geek so progs like Reaktor, Audiomulch, Bidule etc all fascinate me. I have to discipline myself not to disappear down the damn rabbit holes these things represent.
I have Absynth and its useful. A softsynth with a real character. But I usually turn to Dimension Pro and Rapture for a digital quality and UltraAnalog or DCAM for that VA sound these days.
I do miss my hardware but this software does me fine (not that I have any choice in the matter). Actually its the tactile aspect of hardware I miss more than the sonic differences.
Reaktor provides opportunity to get into DSP programming. Assuming I ever have the time...
Age and treachery will overcome youth and skill
