Sonoma 2beJack - Physical Tube Audio for your iPhone and iPad

via Sonoma

"Weeks in development, 2beJack (pronounced "tubejack") is about to revolutionize audio recording on mobile devices. Using proprietary nano and micro-transformative tube technology, 2beJack is the most advanced audio interface ever designed using tried and true audio components of yesteryear. Small enough to fit in your pants' back pocket, the delicate glass 2beJack delivers classic tube warmth to your digital mobile recordings."

Don't put it in your pocket.

circuit bent AKAI S2000 SAMPLE GRINDER + internal SCSI

via this auction
"Many people would suggest that the Aksi S2000 is a rack mounted version of the S20, but this is far from being the case. Its more like a stripped down version of the MPC2000XL without the pads or sequencer, or even a somewhat crippled S3000XLThere are still plenty of these machines still in service in studios all over the world due to the indestructible build quality and that fact they just work, and carry on working...

We have added 9 x 3 way switches to create an 18 way BEND BUS switching matrix that grinds, chops, distorts, bit crushes and splices the samples in memory in all manner of extreme and unlikely ways. More information on the switching matrix setup can be found HERE. Theres no space anywhere behind the front panel other than just above the floppy drive so the switch positioning was dictated by where it could possibly fit.

The switches can be activated at any time and in any playback mode to effect the samples. With more than one sample in memory the sounds tend to react differently depending on how much RAM is used and the numbering of samples, often splicing or chopping two samples together or, in the case of stereo samples, effecting each side of the sample differently. The switches can also be activated while sampling for different effects.

The only drawback to these mods is that the switches can be somewhat permanently destructive to the audio if you're not careful with them, Often the samples will return to normal when no switches are activated, but using the switches in certain combinations tends to slowly degrade the samples in memory and you change switch settings, until eventually everything has descended into a crushing wall of noise. This isn't really a problem if you are using the machine as a kind of standalone sample grinding tool as the fact that it has SCSI means that you can quickly load sounds back in off a Hard Drive or Zip Drive, or even transfer them from you computer based sample editing software.

Mysteriously the standard S2000 doesn't have internal SCSI, but it does have an empty space on the motherboard for the SCSI connector and power. As you can see from the photo below, this space is marked 'S3000XL only'!

We have added an internal SCSI connector to this space which allows you to either remove the internal floppy drive and replace it with an internal SCSI zip drive, or add an internal hard drive. Word has it that S2000 will only format a hard drive to 524MB, but thats plenty of space to save a sample bank to reload it if the mods destroy it in RAM. The S2000 also has external SCSI as standard so you can easily connect an external drive or computer.

Unlike every other Akai ever made, S2000's have a built in mains cable which can be incredibly annoying as its inevitably going to be the wrong length. We have removed this cable and added a standard IEC 'kettle lead' mains socket.

Listen to the demos below below to hear the kinds of sounds that this thing can now produce. The first is a stereo vocal sample, the second is a break loop and the third is a loop made from several different layers of samples.

There is no external effects processing on these demos. All effects are produced using the switches on the front panel"

"This time there are a couple of external circuit boards feeding different signals into a modular synth system. One is a home made theremin, which doesn't work very well (see photo for screwdriver potentiometer!) but produces an interesting waveform. The other is host to a Savage Innovations Soundgin speech synthesizer chip."
