Electric Glockenspiel

Just found this in the attic…

Glockenspiel (1)

I built it when I was about 15, but never finished it. The next step would have been to install a midi interface…
It is a solenoid controlled glockenspiel and still works pretty well.

It sound great and I guess I will build a nice little midi interface, you can actually control the sound by alternating the duration of a keypress (keys are on the back), or hold it to dampen the sound.

Some nice velocity sensitive interface, the current through the solenoids possibly controlled by pwm should give some nice results 🙂

How NOT to replace a battery

Posted on by

A while ago I made a post about the importance of battery replacement in polysix synths.

I just found a great example of how not to do this in a Korg DW-8000:

Horrible!!

Instead of a CR2032 with attached solder tail, somene soldered leads to the battery directly causing it to heat up way to much. This damaged the battery and caused some leaking eventually. The battery acid destroys sourounding traces, vias and even ICs – very bad…

Much better to do it like this:

Hi,

I’m in New Zealand at the moment and not available for repair, mods, etc…..

I’ll let you know when I’m back, probably end of 2012…

In the meantime just try it here:
Schraub und Dreh

Thanks

My new 606 mod. I included some features that I think are new to the world.

Cymbal and open hihat got an attack/decay envelope which is fully sensitive to velocity. This gives you independent control over the attack and decay times and the volume of the instrument.

Also I added a ring mod variant to the existing six hihat/cymbal oscillators using XORs. Gives you a great range of metallic sounds.

Audio soon to come…

Features:

-Open Hihat attack, decay [velocity sensitive!!]
-Cymbal attack, decay [velocity sensitive!!]
-Control pitch of two oscillators for the cymbal and hihat metal sound
-Chose hihat sound to be, oscillators, two oscillators with ringmod, four oscillators with ringmod, mix
-Adjust hihat highpass
-Adjust cymbal highpass
-Adjust hihat+cymbal bandpass
-Adjust cymbal bandpass
-Low tom pitch
-Switch tom noise
-Snare noise amount
-Snare tune
-Snare decay
-Snare highpass filter
