Yes. All of them suffer from the same defect. The ribbon membranes that connect the control surface to the circuit boards have become brittle with age. That means vibration will cause them to crack. Resulting in loss of buttons. I imported one from the USA to Australia 2 years ago. Repair is 100% po...

Ok Weird.

After a couple of hours the problem has corrected itself completely.

Maybe it's a power supply issue?

By the way this isn't just an annoyance. It sounds exactly like the filter is being modulated by a high frequency oscillator when the resonance is cranked. The distortion seems to constantly build and decay at low frequency. Resonance is completely out of whack. Calibration does not resolve the issu...

s**t!

This just happened to my tetra.

After jamming for about 2 hours.

Let me know what Dave Smith says?

I think it overheated.

There's an automatic calibration procedure for the tetra. Try that.

Got mine last week. What I have noticed: Sounds very close to my matrix 6r (which i sold a while back), which is a good thing, i wasn't expecting it to sound as close as it does. Oscillator slop doesn't do much for fattening up the oscillators, it does give a beating VCO feel though. Sub oscillators...

All parameters can be controlled via midi. Also all knobs transmit midi as well (or so sayeth the manual). The midi cc values are naturally fixed. So provided you can configure your controller keyboard to transmit midi CC corresponding to osc 2 pitch, then no problems. The mfb synth 2 has inbuilt ro...

Mfb synth 2 doesn't have the punch, or snappiness that you'll get out of the lil phatty or mopho.

I love my mfb synth 2 to death though, great vcos, great filter, just not the best envelopes in the world.

Adamstan the Greatest!!!!!

It's ok. I sorted this problem out a while ago. Twist removal fuses.

One of mine was broken, hence it didn't want to come out.

Any idea how many 2044's are around? They sound fantastic.
Would love to design a synth using them

Strange that you're not getting any lights or anything. The main output of the 909 is quite noisy so the noise you're hearing could be an indication that the analog circuitry is getting the power it needs, where as the controller board is not. I assume it's a power problem. Might be worth checking t...

Also does anyone know how to remove the AC fuse from its socket. The other 2 are simple twist mechanisms but this one doesn't want to come out.

Do the fuses on a Minimoog Model D need to be changed in order for it to run on it's alternative voltage setting. I'm switching it from 115v to 230v AC.

Try auto tune. It usually re-calibrates the voices so that they work. If voices are still missing then you probably have a hardware problem.
