Problem with PEK (OSC 1 of 4th voice broken...?)

2006-09-15 by Tom Prayne

Hi,

I was just about to send this to DSI support, but maybe here also  
somebody has an idea...?

I just bought a PEK and received it today.

When playing it, I noticed that the 4th voice sounds a bit different  
than the others... I checked with the "Basic Program" in memory slot  
128 and solo'd each oscillator. It seems like OSC 1 of the first  
voice would have a problem - when playing the same key four times in  
a row (with OSC 1 L solo'd), I don't hear anything (or just a very  
soft signal) when the LEDs on the right side of the Evolver indicate  
that the 4th voice is used.

The other three OSCs don't behave like that, they play on every voice.

I sent out 1/4th notes from my software sequencer at Velocity 127 and  
recorded the Evolver's audio output with Basic Program 128. I made  
sure that the first note is always played by the 1st voice.
There are 2 files - one with all OSCs of the Basic Program patch and  
one with OSC 1 solo'd.
I don't have any of the single voice outputs on the backside of the  
Evolver connected, just the stereo main out.

Ip uploaded the recorded audio files to my website, so if anybody's  
interested...:

Do you have any idea...? Is this a hardware failure...?



thanks & greetings,

Tom
