<div dir="ltr"><div>On one Jupiter 6 I did, I was convinced the RAM was bad because no matter what there would always be a few corrupt patches that would lock up the synth. Eventually I figured out the patches that failed had to do with the level I was doing the playback at, and it was consistent across every interface I have - the only solution was giving the tape signal an absurd amount of gain thru a preamp. If I recall the dump I got online was already normalized, and the cassette interface on the synth had no issues, so unless the CPU had a problem, it was possibly due to the frequency response of the specific dump or something like that. Ever since then I've done cassette restores on Jupiter 6's by giving it a ton of gain thru a mixer channel, and haven't had any patch dump issues yet. All that to say - don't rule out cranking the gain like crazy. </div><div><br></div><div>I've also had to do what Tony describes to get JP-6 memory to work correctly <br></div><div><div><br></div><div>Nathan</div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Aug 7, 2024 at 3:28 AM Tony Allgood via Synth-diy <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I have seen similar behaviour before with various JP-6 units over the <br>
years. What has always fixed it is going into manual mode. Create a <br>
simple standard 'init' patch, something like a classic analogue pluck <br>
sound will do. But it doesn't matter - just something you know the sound of.<br>
<br>
Then program that same patch into *every* memory location.<br>
<br>
Now check every patch still sounds the same and no crashes occur.<br>
<br>
Reload the factory patches via tape if you wish.<br>
<br>
However, if it is your own patches you are trying to load, then it could <br>
be that it is those that are corrupted. In this case, it is probably <br>
better to reprogram those sounds in manual mode.<br>
