CATWEAZLES Fraktal / CellilarAutomata Synth

[Gordonjcp]

Has anyone got the demo MP3s?  Does the source for the firmware exist anywhere?  It would be a shame if this was lost...

[ultra]

i found a link to this a few days ago.  i really want to hear the sound samples but the site hasn't worked!

can i get them anywhere else?

[catweazle]

Hi folks,
my server is down, sorry ...  but someone asked me to post the PICSYNTH in
the electro-music.com forum:
http://electro-music.com/forum/topic-25422.html
Here you can get all schematics, source and hex files.

Sound-Samples:
ahm, I still have no server, so if I have a new one I upload the samples again.

For questions and suggestions you can mail me:

Good luck building and having fun with it

Thanks for reminding me, i've also uploaded the construction files to the circuitbenders server if thats cool with you catweazle?

it can be found here http://www.circuitbenders.co.uk/hostedstuff/picsynth_v11_191.zip

theres some demos of mine at:

Yep, of course, thanks for uploading.

On the electro-music forum you can found some more sound samples from somebody else.
(should be no advertising for other forum, only a hint)

Catweazle - mail me off-forum or pm me if you want some server space ;-)

PICsynth plans and audio samples are available again...

[djsynchro]

I found a place where they program the PIC for 3 Euro if you don't have a programmer.
Will be building this! Hey Catweazle any plans for Midi?

[catweazle]

Hi djsynchro,

any plans for Midi?

Nop
I've thought about Midi Clock but I don't know how to sync the algorithms easy yet.
Parameter control via MIDI is theoretically possible, but it's easier to buy a MIDI to CV converter
and connect that instead of the pots (highly liquid or something). The pots are nothing else than
a control voltage (0..5Volt).

Maybe I'll find a way - but I make no promise.
It's more a fun toy than a high end synth (and toys don't have MIDI

[Gordonjcp]

What's the new address for the plans and samples?  I had a look in the obvious place but it just said "8 bits are enough"...

I've got a Doepfer that has 4x  0..5V CV outputs so I can try to hook that up, cool.
Toys do have MIDI... I'm currently building Highly Liquid kits for my Speaks, my Atari2600 and my SK1.

I never really thought I wanted MIDI because the bent sound is only the 1st stage, everything ends up as audio in Ableton Live and gets sliced/diced/warped whatever some more.... but I saw a vid of a MIDI 2600 and I was like "wow", I think MIDI control will get me to where I want to be sooner.

Hey how about a trigger input (+5v gate pulse?) so the sequencer advances one step... that would work and it would save you a lot of boring MIDI programming...?

[catweazle]

  ok, maybe some toys have midi, damn...
good idea trigger for step advance... I'll do that if I got my synth back (lent it a friend)
synching the thing seems to be a important requested feature.
... wishlist is long...

[djsynchro]

Trigger for step advance would be awesome man!
Saves you writing all the boring MIDI crap (might not have enough CPU cycles left for that anyway?)

I'll just use the gate of one of my Midi-CV converters, and I guess most folks around here will know how to knock up a trigger signal.

I am having so much problems trying to program the chip. I have a pickit 2. does anyone know of a low cost demo board which could program it, or a cheap programer that works?! thanks x
