<br>
</div>
<div style="background-color:#FFFFFF"><font face="Arial">In case anybody was wondering about these...<br>
<br>
Received my order of new CEM3340s from Onchip.<br>
<br>
Installed some in my P5 and Pro-One (mixed in with original chips)-- waveforms sound the same, response to PW & pitch mod is the same, tuning & scaling are the same.<br>
<br>
Installed them in my P600 (running firmware v6.0.8) and they tuned & scaled just fine.<br>
HOWEVER, installing the gligli firmware upgrade caused the oscillators to go wildly out of tune.<br>
Replaced the 26.7K trim resistors with 25.5K 1% (as per the service manual instructions on using revG chips), and running the gligli tune routine solved the problem.<br>
<br>
I realize that one point on a graph doesn't give the most accurate information; if anybody else is using these as replacements in vintage synths (Roland, SCI, etc) it would be helpful if you report your experience to the list.<br>
<br>
Thanks.<br>
