"Introduced in 1994, the E-MU UltraProteus is a Z-plane synthesizer with 16MB of ROM samples comprised of five preset banks. The first three are internal with the last two being accessed via the front panel card slot. This slot is PCMCIA compliant and accepts either ROM cards or user RAM cards. Each of the five banks contain 128 presets. The hyper presets are used for layering other presets, or setting up keyboard zones for using multiple presets with different keys.

Bank 0 — User RAM presets
Bank 1 — ROM presets
Bank 2 — Hyper presets (User editable)
Bank 3 — Card presets *
Bank 4 — Card Hyper presets *
* if using a RAM card, banks 3 and 4 are user editable.

The UltraProteus is based on the same engine as it’s sister, the , but an entirely different sound set and additional filters (288 compared to 197 in the ).

Extra ROM Cards:

QTY: 2 9211 – Proteus 1, 2, 3
QTY: 1 9072 Plus Power (MPS +)"

Korg Poly 61M Vintage Analog Synth with MIDI SN 001636

via this auction

""Unlike many Poly 61s that are out there, this one is not all bashed up. The body is in great condition, with only a few minor nicks, and the synth is in very good working form. It has never had a battery leak, so all the functions work perfectly, and I did the following to it, to get it in top shape:

- I replaced the original battery with a CR2032, in a battery holder on a longer set of wires to make changing it easy.
- I totally refurbished the keyboard, cleaning all the keys, cleaning all the contacts, and adding carbon discs to the contacts, as per the solution by Sounddoctorin.com. That brings all the keys to perfect working condition.
- I removed all the tactile button switches and replaced them with brand new ones. That solves the annoying problem of having to keep hitting the program buttons many times until they work, or having them double count because of contact bounce. Now all the programming buttons work flawlessly. There is a photo showing the new switches(blue) on the two switch circuit boards.
- I cleaned all the pots to eliminate scratching noises and jumping values.
- I replaced any of the screws that were missing, and all the feet are there, too.

This is a really great sounding synth, with a pure analog voice signal, and very stable tuning thanks to the digital control of the oscillators. And with factory midi, it is just a dream to own. It is fully tested, and loaded with sounds from a file I downloaded onto my phone from the internet. There are lots of those out there, and it is easy to do. And of course, you can create and save your own sounds."

ESK - Marble Physics Modular Demo Update

Metunar's recent ESK - Marble Physics Modular Demo in this previous post has been re-uploaded.

Black Corporation's Roman Filippov Introduces Buchla format 288r Time Domain Processor

This one is in via Black Corporation's Roman Filippov:

"I'm starting a preorder for a limited run of 288r - my approach on the Time Domain Processor, the digital version of it.

- 24bit/196KHz sound quality (switchable to 12bit "vintage" mode)

- up to 40 seconds of looping buffer (switchable to original short loop timings)

- both timing and phase/mixing presets are set up by trimmers and dip-switches on a back of a module, no need to wire or change resistors

- preorder is $299, total price is $1099 shipped

- a usb-programmer for firmware updates will be included with each order

- source code will become public shortly after the release of a module

- shipping is scheduled for mid-march 2021

- this is one-time run and i'm not offering kits atm unfortunately

- couple more cool modules to be released later this year.


reservations are via PayPal only, please PM or email to in@btwn.us if you want one"

According to fluxmonkey, the original Buchla 288 8-stage voltage controlled looping digital delay never went into production. Only 2 prototypes exist. Mark Verbos of Verbos Electronics created a version using different circuitry.
