[sdiy] Oberheim 2-voice

[Steve Carter]

Is anyone in the group familiar with the Oberheim 2 Voice synth? I  
have just finished renovating my 2 voice - both SEMs were riddled with  
faults (mainly defective ICs), so was the sequencer, the mixer and the  
keyboard controller.  Originally the power supply had failed causing  
most of the damage.  Anyway it's all set-up and working nicely now. So  
I'm playing away thinking how good these Oberheims really are and it  
struck me that there is no CV from the keyboard controller when  
playing other notes whilst holding the first note down.  The duophonic  
bit works fine, sending independent CVs and triggers to each SEM when  
holding two notes down but in 'unison' mode it's one note at a time  
and key lift off in between. In 'unison' mode I thought it was meant  
to be high note priority based. It's so long since I've played this  
synth that I've honestly forgotten but I do remember being able to  
'roll' those bass lines which I can't do anymore.  Is it my  
imagination? This is a late model with the digital keyboard controller.
