DSerial - MIDI In/Out for the Nintendo DS

via natrum42
"Posted schematics, pictures and brief instructions for connecting MIDI input and output to DS to the DSerial Wiki. MIDI output is very easy, because it requires no components besides wire and a 5-pin DIN connector. MIDI input, on the other hand, requires a 3.3V optocoupler because MIDI uses a current loop to prevent introduction of noise."

"There are a few different sequencers out there for it. Here's a couple:soundpunk.com, nitrotracker

There's also a project that lets you do MIDI over WiFi or with DSerial: http://dsmidiwifi.tobw.net/"

"This was and still is a very popular analogue synth. Apparently 'DEVO' were the first group to receive the first two of these ever made from Roland themselves."

Anyone confirm or deny this?

"original keyboard stand manufactured by Arp in the late 1970's early 80s. These are always seen in ads for the Odyssey and Omni synths. Made of steel, breaks down into 4 pieces and ships flat. Weighs 20 pounds. This one has standard nuts (not the threaded plastic wheels in the ad)."

Casio SK-1 Sampling Keyboard Synthesizer

Update: And the joke is lost for this one. The auction link went to the auction post for this Simba Lego set but was miss-titled as the Casio SK-1. When I first saw it, I thought someone actually pulled the guts out of an SK-1 and built this as a custom case. I then realized it must have been a mistyped auction. I put the post up with just the link so you could share in the experience, but no the link goes to Vintage Tupperware Popsicle Molds. :) The actual auction for the SK-1 is here.

Polivoks

images via this auction
"Very good for agressive bass, weird modulations, cool FXs & agressive sounds. Impressive fat saw & cool glidings. Killer 2-Voice mode.

2 VCO with classic waveforms, noise oscillator and external source.

Very strong sounding Analog LP/BP filter with ADSR Envelope,
which can play in loop (retrig). You can process external sound through it,
such as guitar, vocal, drums or another synthesizer. Because of FILTER sound of POLIVOKS is so unique and strong/

Amplifier section contain Envelope ADSR with loop function (retrig), modulation & bypass mode.

Modulator section is a low frequency oscillator with multiple waveforms
and changable rate. LFO roots to amplifier, filter, VCO-1, VCO-2.
Polivoks can play like a classic monophonic synth or in 2-voice mode.
And also You can modulate VCO-1 with VCO-2 (ringmodulator).

No pitchbend & modulation wheel.

Cool design. Very solid. Hard aluminium body & case - it's Bulletproof I think. (It's a joke. Do not try this @home ; ))
All words printed in cyrillic - so it's very unique too.

There is a custom made CV/gate modification on the board (1 voice).
Now You can connect analog sequencer (1 volt per octave)
This is very usefull function. Feel free to use it with Your analog sequencer.
I had use it with my Roland TB-303 sequencer.

CV/Gate - is the first step to MIDI . You can find in the web how to do that.

Of course You can play with keyboard.
There is a tumbler.
Choose CV/gate or Keyboard."

"Circuit for using a CD4046 PLL to generate a voltage controlled BBD complimentary phase clock! I found this ripped out page on it's own in a stack of magazines I purchased Yesterday; Sunday 18th of May, 2008. The previous owner was interested in the other side (some notes on there in pencil).

Thanks to Hugo Bramall of Canterbury, Victoria who came up with the circuit and sent it ETI magazine in the first place! "
