ACME XP60 - Oberheim Xpander Clone In the Works

Spotted this one on Amazona.de.

The following is Google translated from the article:

"The ACME XP60 has set itself an extremely ambitious goal: the polyphonic synthesizer is to be nothing less than a 'faithful replica' of one of the greatest vintage classics: the Oberheim Xpander. The project by developer Markus Malik, who has so far offered modifications, replacement boards and repairs, is actually already in an advanced phase.

ACME XP60 - a compact Xpander

Admittedly, given the name ACME, you might think that the whole project is just another hoax report that comes around every year. But the XP60 is real and the electronics of the prototype are ready, although according to Malik there is still some need for optimization in the layout of the circuit board and the power supply.

Like its role model, the XP60 is also a six-voice analog synthesizer. However, the design is smaller, because the device, which actually has a desktop format, also fits in a 19" rack.
Not only the structure of the sound generation was adopted, but also the operating concept with the three displays. One improvement, however, are the controls with LED rings, whose colors can be customized.

For the sound generation, modern counterparts (clone chips) of the CEM3374 (Dual VCO) and CEM3372 (VC Mix-VCF-VCA) circuits used at the time are used. As a reference, developer Markus Malik was able to build the voice cards for the prototype with original oscillator ICs. In blind tests with mixed operation, no differences could be found between the original and clone chips.

There were also attempts to discretely recreate the circuit of the IC with transistors, but despite adjusted values, there were no satisfactory results in terms of temperature stability and FM, so this approach was not pursued further.

Doepfer, among others, has shown that the implementation of the complex multimode filter with its 15 different filter types can be successful with the A-106-6 XP VCF module.

Initially, no new firmware was written, but the original OS was used during development. The firmware is very complex, as envelopes, LFOs and other modulation options are also implemented using software. Tom Oberheim's consent was requested for the use of the firmware.

If the original firmware is retained, this will also entail certain restrictions, as it does not include parameter control with MIDI CCs, for example, but only Sysex. The developer may not be able to avoid creating his own OS sooner or later.

A small series of 50 units is planned initially, but a continuation is not ruled out. Information on the release, distribution and, above all, the price of the ACME XP60 cannot be given at this time, as there are too many factors that could still influence this.

So there is still a lot to do and we will report on the further progress of development."

Favourite Synths : Episode 1 : Roland SH-2

video upload by Luke Million

"This little beast from 1979 often flies under the radar, but it's a powerful monosynth that will put a smile on your face.

My SH-2 is connected to a RE-201 Space Echo and recorded through a Universal Audio Volt 476."

PPG Returns with W2.2x4 Eurorack Module

Press release follows:

The legendary German synthesizer brand PPG is making a comeback, thanks to the collaboration between Cornel Hecht (Hell Modular) and the Liquid Sky Artistcollective (Liquid Sky d-vices).

The first release in this revival is the W2.2x4 Eurorack module, a 3U dual wavetable oscillator featuring all the original wavetables from the iconic PPG Wave 2.2. Each oscillator is equipped with a sub-bass generator, overdrive, and a built-in VCA, delivering the classic PPG sound in a modern modular format.

The PPG W2.2x4 can sound extremely true to the original or introduce new sonic nuances through its VCA/overdrive section.

It is suitable for all genres of electronic music, including Techno, Synth Pop, Ambient, Industrial, Noise, Berliner Schule, and more.

The W2.2x4 module will be available in two editions:

Limited Edition: Black front panel, strictly limited to 127 units. Shipping begins this month.

Standard Edition: Blue front panel, unlimited production. Shipping starts before Superbooth.

Additionally, the Liquid Sky D-Vices GLITHc ExpendR is compatible with the PPG W2.2x4, transforming it into an experimental mini glitch/noise/wavetable remix lab.

With its unique sonic character and heritage, the W2.2x4 brings the spirit of PPG into the contemporary Eurorack world. Be among the first to experience this modern classic!

DIY Analog-Hybrid Synthesizer with Rene Schmitz Vakuum-Tube VCF

video upload by Andreas Remshagen

"At first I wanted to build a complete vacuum tube synthesizer but I had problems with the vacuum tube VCO and the correct intonation over several octaves. That's why I decided to build two AS3360 chip VCOs and run them through a vacuum tube mixer. I used Rene Schmitz's vacuum tube filter as the VCF. ADSR, VCA and ring modulator run on AS chips.
