Alternative Firmware ROM for the Yamaha DX9 Brings it Closer to the DX7

You might remember this video from Espen Craft on how the Yamaha DX9 is essentially a 4-Op DX7. The DX7, of course, is a 6-Op FM synth. ajxs on Github is working on a ROM that will update the DX9 into a 6-Op synth a pitch envelop generator to more closely match the DX7. Details follow:

"DX9/7 is an alternative firmware ROM for the Yamaha DX9 synthesiser. Its aim is to uplift the DX9's functionality to more closely match that of the DX7. It restores features that were intentionally restricted in the firmware, such as increasing the operator count to six, and adding a pitch envelope generator. This ROM makes the synth properly patch-compatible with the DX7.

This is not a patch for the existing DX9 firmware, it is an entirely new firmware ROM. It has been assembled from the original binary, together with code from the DX7's V1.8 ROM, as well as new code written from scratch.

New Features:

Makes the DX9 able to play DX7 patches.
Restores the use of all six operators.
The synth is now sensitive to the velocity of incoming MIDI notes.
Implements the DX7's pitch EG.
Implements DX7 style operator scaling.
Implements DX7 style portamento/glissando.
What is the current status of the ROM?

This firmware is currently highly experimental. Although the main features are fully working, testing and bugfixes are ongoing. Installing the firmware for everyday general use is currently not recommended. As additional testing is performed this will improve. If you do intend to use the ROM despite this warning, please refer to the section on reporting issues. Development, and testing of the cassette interface is ongoing, and at this point it should only be used for testing purposes.

The risk of any harm coming to your DX9 as a result of using this ROM is incredibly, incredibly small, however the developers take no responsibility for any issues that may arise as a result of using this alternate firmware. All care has been taken, and considerable testing has been performed, however the developers accept no liability for any issues.

Hear the Futuristic Synth Everyone's Talking About - Osmose Sound Demo - No Talking

video upload by Perfect Circuit

"Several years in the making, Expressive E's Osmose is one of the most unique keyboard synthesizers available. Using a cutting-edge keyboard design, it can detect multiple levels of pressure, left and right movement, and more...creating a tremendously expressive playing experience. Paired with the onboard Eaganmatrix sound engine, you'll get everything from classic synth pads to uncanny physical-modeled tones—and frankly, it'll make you re-think the way you play a keyboard altogether.
Plus, it makes one heck of a MIDI controller, complete with MPE capability. If you need a futuristic synthesizer or controller, there's simply nothing else like Osmose.

love on a real train // mc-707 cover

video upload by geomagnetics

"This is a cover of the great Tangerine Dream song. I wanted to stick close to the original version while keeping it strictly on the MC-707 and not use external gear. I've loved this song for as long as I can remember but covering it gave me a whole new respect for what they did in those studios before computers and grooveboxes.
I sequenced it all except for a few sweeps and fades which ends up pretty boring to look at. So I threw in some holiday footage"

Tiptop Z DSP feedback

video upload by Todd Barton

"A simple feedback patch to listen to what is inside the various reverb algorithms of the Halls of Valhalla card for the Tiptop Audio D-ZSP Digital Signal Processor. Of course you are just hearing the same Decay/Tone/Chorus knobs setting for each iteration. So much more possible by playing the knobs. And, of course, more various sonic universes with the other cards.
Enjoy!

"3 oscillator semi-modular synth, complex modulation capabilities, MIDI & CV control.

Probably no other monophonic analog synth has this amount of sound bending capabilities at your fingertips on an ultra-compact footprint. Directly prepatched and switchable are:

VCO2 synchable to VCO1
VCO3 can modulate either VCO2 (only) or VCO1 + 2
VCO3 can modulate the filter
VCO3 can be taken out of the audio path completely, becoming an 'invisible' source for modulation only
the filter envelope (VCF) can modulare VCO2 ('sweep VCO')
VCF has two modes of keytracking
both LFOs can control VCOs AND filter cutoff at the same time and with independent settings
LFO1 can do S&H by sampling LFO2 (making them interdependent) or the noise generator
oh, there actually is an "OSC4" which is white noise (with its own level control), in addition to the white noise setting on VCO3 and the white noise setting on LFO2. That's 3 noise generators in just one synth.
glide function
VCA switchable positive / negative
envelope trigger switch
...
In addition, there are the patch points which add PWM modulation, external audio insert points, individual VCO outs, V-gate in on LFO1 +++

Condition:
Fully functional. Great overall cosmetic condition. Very few signs of use. Some hairline scratches around the sides, particularly the front. Hardly visible – see photos.

In Europe, this comes with a 12V AC 1A adapter (EU-style plug – 230V). Not switchable! Will NOT include in North America / Japan sales to save on shipping weight. You'll need to buy one that works at your local voltages."
