MB-SID Patch Challenge #1

[Wilba]

I can craft some cool patches with my MB-SID, but I'm not that good at trying to copy a sound I've heard somewhere else.

For example, check out the Moog Little Phatty and the sample called "Robot Sync".

It's an awesome looking synth, and only Moog could market a two-oscillator mono synth these days and get away with it  ;)  and surely a humble SID could produce something close to this "Robot Sync" patch, right? But for some reason I can't quite get it...

There must be someone here who knows how to get this kind of sound out of a SID... so here's...

MB-SID Patch Challenge #1

Make an MB-SID patch that sounds like Moog Little Phatty's "Robot Sync"

http://www.moogmusic.com/detail.php?main_product_id=227

(click on the little ">" button to scroll through the samples)

There has to be a prize for achieving this... I'll give away a spare PIC18F4685 (for MB-SID v2). Maybe I also will give away a 6581R4AR (which might have a dead filter, I'll have to check).

Terms and conditions: The judge's decision is final. I am the judge. There can only be one winner. The patch that sounds the closest to the challenge patch will receive the prizes, but it still has to sound like the challenge patch, i.e. if I only get one entry and it's nothing like the challenge patch, no prizes will be awarded. Prizes not redeemable for cash. The winning patch may be tweaked and included in the default patches for MB-SID v2 (with credit).

You may be a little out of luck with a SID, it sounds like part of this a high resonance Low Pass Filter swept by a note triggered envelope. Other part is some kind of two osciullator soft sync, at my best guess.

I don't know enough SID yet, to know if it is possible.

The 'Little Phatty' is definitely the Mini-Moog for the 21^st century.

On similar lines, I hope I can get a SID to do something like this: http://www.colinfraser.com/m5000/syncron.mp3. This is only a partial sample, because I haven't got anywhere to 'park' one of my own. It's an early digital, the 'Music 500' add on for the BBC Micro, which had a discrete component DCO system in it.

It sounds to me like a sync'd square wave (both osc's), with PWM routed through the envelope to the pulse width of OSC2 (the slave). I don't even thing that the filter is being used, sounds like it's wide open.

My guess, if it's achived like it is on the Prodigy:

Set osc 1 to square wave (50%) at 32' , sync it to osc2, Square wave at 16' and assign one of the envelopes to modulate the Pulse width (in the case of the prodigy, you set that to modulate the pitc of osc2).
