Pitch mod wheel range problem

Pitch mod wheel range problem

2013-03-29 by scituate_mass

Hi everyone,

I just resurrected a 101, Seems like it is working OK, but my mod wheel is behaving oddly. I get good behavior right to the extremes, and then it suddenly either jumps to an extremely high pitch when turning high or an extremely low pitch when turning low (I'm assuming, since it goes silent).

Is there some calibration for this? Or would someone know what component might be suspect?

Thanks,

D

OK... this is weird. After an hour of fiddling with it, it suddenly started responding to the mod wheel range control. Now it just works - no bizarre high or low note. Anyone know what may have caused this though? I'm still curious... and sort of waiting for the problem to return.

On a side note, for those interested, a jumbo sized paper clip makes a perfect replacement (once bent into an M shape) for the positive battery terminal (mine, like many was corroded from battery acid).

best,

DT

Whenever my batteries die on my cz1000 i get odd mod wheel behavior, so it may be software not hardware causing this. check that pitch mod range is set to a reasonable amount-12 semitones or 2 semitones are the 2 most common standards in synths

I can tell you this:
Every time I turn of the CZ1000,with no battery backup - the parameters go out of range,resulting in the kind of effects that you are talking about. Moving the data in the LCD resets it to WITHIN range,as does pressing the P reset underneath the unit.
So it sounds like a backup power scenario.

I've read that some people have found "Easter eggs" including undocumented waveforms and unusual envelope behaviour in that mode, so it may be worth investigating if you can access it reliably. In the 1980s I had a Casiotone CT-202 which, once every 20 or so times when you switched it on, came up with a strange mode where each key had a different sound, made at random from the components of the 49 presets.

It maybe a flaw of the on power state not resetting the RAM,the sheer fact that there is a P reset button on the base,suggests that it is not reset on power on. 
From this audio track:

http://www.youtube.com/watch?v=GpO-oUx9ul0

it sounds like the 202 had sounds assignable to keys (for whatever reason) and therefore could conceivably have had different sounds on keys.

One "easter egg" that I know about is the FZ1 hidden menu which is released by holding DISPLAY at power on.

Yes - that's exactly how it worked. Each key doubled as a sound selector, and there was a select/play switch. Percussive sounds (piano, guitar, koto, banjo etc) were selected by white keys while sustained sounds (organ, accordion, viola, horn etc) were chosen by pressing the black keys. A simple system that worked well, especially since you could also assign any four sounds to push-buttons for instant recall.

But when it went wrong, it would play scrambled sounds (mixing the attack and sustain/decay tones differently) in play mode.

Thanks for all the replies. I haven't been able to replicate the issue... weird.  Now struggling to find a battery that will fit in my RAM cart. It won't take a holder, no one sells batteries with solder lugs in Sweden (where I am), AND no one will ship the damn things to sweden because it is "illegal" to ship lithium batteries. Sigh...  

Anyone know of any super low profile battery clips? everything I find is too tall.

These posts also reminded me of my 202 that is sitting in the basement waiting for a new vibrato four position selector switch (which I had trouble finding before). Those early models had such cool sounds. All the wood grain models up to, but not including the 601 were great (the 601 had that sine wave nonsense - all the sounds sounded the same). Time to dig it out and fiddle again...
