Tiptop Audio Going Polyphonic - 8 Voice Module, CS-80 in the Works?

Bits from Gur of Tiptop on Muff's:

"It's a huge design project but It's all going well so far. Feels like laying bricks, one at a time, and slowly a new sticky ugly creature is emerging. zombie

The pvco pcb layout is almost complete and I should be able to order the prototype pcbs some time late next week. This one is probably the most challenging design in the P series and so far it all looks good.

We also finish developing the firmware and hardware for a high precision frequency counter and tuner that goes into the pvco and is used to count the frequency from each core separately, making a smooth process of tuning and calibrating the oscillators. That was a descent size project in itself that took some good amount of time and resources.

Next inline is the pvcf, and here I'm debating what to start with, a 24db Z2040 (Prophet 5 V.2) style topology or a OB-X 12db style topology. The OB-X should be cheaper to produce so I feel it will be wise to start with."

"...the first oscillator module is analog, saw core. As for the filter, I'm going to try and play with the OB-X schematic and see if I can pull up a HP output as well. That will require some internal signal routing and as long as it doesn't add too many parts then I might go for it."

"28HP for this one."

"The PVCO is 28HP, then we have Filters, VCAs, ADSRs........ Most of them should be lower HP."

"it will be a sub-format of euro. Same panel sizes, same power connector, and runs of euro +/-12V. I have no doubt that other manufacturers will jump in as soon as the format has been realized and proven. That will be sooo awesome. No need for 8 cables, one cable will carry 8 signals and a shilled"

Then go for it, A poly CS-80 is in the pipe. I think that filters will be a really big thing in this new format."

FB01 custom sounds example

YouTube Uploaded by alexmauer on Mar 14, 2010

"This is a demonstration of the custom sounds I made for my Yamaha FB-01 using the Atari ST program "Caged Artist FB01 Editor". As you can see... its possible create drum sounds similar to what you'd hear on a drum synth, as well as create typical FM sounds... and even a very clear sounding square wave. I am sure someone will comment with "this sounds like Sega Genesis" and I agree mostly.

PS - there are no external effects applied... not that it sounds like there are"

FB01 custom drums (analog)

Uploaded by alexmauer on Mar 28, 2010

"These are custom sounds created using the "Caged Artist" Atari-ST editor for the Yamaha FB-01. Specifically this demo showcases analog drum machine type sounds. If you ask me, these sounds sound better than a Korg Electribe drum synth."

Casio CZ-1000 Custom Sounds Demo (including hidden parameters)

YouTube Uploaded by alexmauer on Apr 18, 2010

"I bought this Casio CZ-1000 for the purpose of live performing. Some of these melodies are from my songs and some songs that I like. Most of these sounds were created in the Caged Artist "CZ Rider" editor for Atari ST. I accessed hidden waveforms and parameters using a hex editor on raw sysex data. The CZ series does not have pulse width modulation by default... you can use tricks to create it."
