"Ellatron - the sound of the 60s in your hip pocket!

Ellatron is a musical instrument for iPhone and iPod Touch, drawing inspiration from the classic Mellotron M400."

Nord Lead 3

YouTube via rpb1966. sent my way via fischek.
"The Nord Lead 3 can re-create a wide palette of sounds, these patches, Vox Humana, Laser Harp and Billys Screaming Lead, were all programmed by myself."

More Nord Lead 3

"Just have a listen, I thought I would do a longer one this time, a nice tribute for Billy for starters, and a few other surprises."

D16 Group Nithonat

"Nithonat is a classic drum machine box (606 emulation this time). All instruments are fully synthesized and with a way more advanced and extended sound shaping capabilities than its predecessor. Whole functionality of Nithonat is very similar to the other drum machines from D16 Group, which makes it very easy-to-use and creative instrument.

Nithonat has stunning GUI kept in the same fashion as well known Phoscyon's interface. Since the both small brothers are back together shoulder to shoulder.

Nithonat is planned to be released as both VST and AU simultaneously. More information about it is coming soon." Note D16 Groups makes the highly respected Phoscyon, Nepheton, Drumazon TB303, TR808, and TR909 emulations. Click on the d16 Group label below for more including video comparisons.

Godwin Supersonic Digital Synthesizer

flickr by Mark Cochrane via bunker on the forum: "Here are some images of my poorly Godwin digital Synth. Its currently built into an SC600 organ but I intend to build it into its own case. I ve never seen one before let alone found any info on the net. It seems to be a hybrid with a digital oscillator and patch storage combined with VCF, non VC HPF, VCA, 2x ADSR, aftertouch, good modulation options and some SSM chips. Problem is no waveform and poorly trigger and gate signals. The microprocessor is an 8035 and I think the problem lies here. I've got some on order at the moment so we shall see. From what I can gather the same micro was also used in the Jupiter 4 amongst other synths, as well as the Donkey Kong arcade game!. If anyone needs one of these chips let me know. they are brand new unused and not pulled from something else."

some additional info from bunker on electro-music.com: "I have a Godwin Digital Synthesizer built into my Godwin SC600 organ. The day after I took delivery the synth died or more precisely the oscillator died. At first I was expecting the synth to be built around the m110 chip that was used in other Italian synths of the time such as the Jen SX1000 and Siel Mono/Cruise. However on closer inspection the synth is made up of 9 seperate PC boards that slot into a motherboard. The basic features are Square/Sawtooth waveforms, LFO controlling vibrato, tremolo and filter, A Low Pass VCF, a High Pass filter (not VC), ADSR's for both VCA and VCF, repeat function, manual control of PWM, spring reverb and a crude form of aftertouch called sensitivity control which affects pitch and VCF. The only digital part seems to be the 8035 microprocessor which controls keyboard scanning, preset control and gate and trigger signals.

Ive poked around and when the board with the 8035 on is removed I get the frequencies that the schematic tells me I should be getting from the oscillator output on the Master Generator board. The oscillator looks to be built around 74132 logic chip and 4558 op amp which, I guess makes it a digital oscillator? With no 8035 however I have no gate or trigger hence no sound. When I replace the board the osc. freq. drops from the 200 odd kHz in the schematic down to About 1kHz. there is a wave form generator that is fed from the osc and this must divide the freq down to normal audio. The gate seems to be "stuck" but with no sound. The filter will self oscillate and the mod controls affect it as does the repeat function so im guessing its the 8035. There is A UV EPROM on the same board but my guess is that this is for storage of the preset patch controls and as all these seem to be okay, albeit with no sound, I dont think this is the problem.

I am still learning my was around repairing and building synths so please be gentle! I want to rehouse the synth in a custom case and modify it with maybe a VCO or two along side the 8035 osc. there are SSM 2020 and 2040 chips on the VCA/VCF/HPF board and there looks to be some scope to really mod this synth or maybe turn it into a fully analog instrument.

If anyone has any ideas or has even seen/played one of these before please let me know. I can see this baby in a cherry or oak case sat on stage being played!" This is only the second Godwin synth posted on MATRIXSYNTH as of this post. Click on the label below for Godwin 849 String Concert.
