SWR Mini Mo Bass Pre Amp vs. Drum Machine

YouTube via Analogger
"I recorded an 80 measure drum pattern using the drums from a Roland SH-32. Mono out into the SWR Mini Mo. The SWR has killer analog distortion and a fat analog bass synth section that tracks your playing really well. That's a different story with the drums - so it ends up sounding like a dirty envelope follower. Obviously the Mini Mo was not intended to process drum loops - and that's the beauty of it!"

KORG DS-10 - My First "Song" - On a DS10 Emulator

"The sound quality sucks because it's on an emulator. I'm aware this is not really good. Hopefully I'll get better with an actual copy on an actual DS :p"

The Persephone

via this auction
"The PERSEPHONE is a high quality fingerboard analogue synthesizer with CV and MIDI in and out. It has the vintage look of a 1920s early electronic fingerboard, but its advanced sensor technology and digital controls combine to create a pure analogue generation of sound.

Musicality is determined by the way it is played; its ribbon control surface is both pressure and position sensitive; finger position on the ribbon zone determines pitch, while finger pressure determines volume, (although this can also be controlled by a separate expression key).

With its 100% analogue oscillator, its lower frequencies go from a deep and resonant cello tone to a nearly human voice. Higher, it can sound similar to a violin (especially when using vibrato), and can reproduce the musical sound and glissando sci-fi effects of a theremin or Ondes Martenot, although much easier to play than a theremin because the linearity of note-spacing is regular, dependable and, of course, tactile giving greater stability of intonation. The Persephone can generate notes with a range of 10 octaves; a scaling potentiometer allows the Persephone's ribbon to be adjusted from 1, 2 and 5 to 10 octaves.

All the controls are digital. The four play modes - A, B, C and D - offer different hierarchy of control between the pitch, the velocity, a filter modulation and a LFO. Tune finetune/brightness : two waveforms wave : from sinus to triangle. Connections are located on the rear side of the front panel. With its CV out, it can control any other analogue synthesizers and modular systems. With its MIDI in/out, it can also be used as a MIDI controller."

Roland GK-1 Synthesizer Driver

images at this auction
"For those of you vintage synthesizer enthusiasts that would like to be able to utilize one of your favorite guitars as a controller without having to drill holes or modify that special guitar here’s the solution for you. With this GK-1 driver package all you have to is mount the driver (with controls), and the hex pickup to your guitar with the double sided adhesive tape that’s already attached to the back of these two pieces. The purpose of the shim is there in case you need to make a height adjustment to the hex pickup and it also has the double sided adhesive tape. The double sided tape (like poster tape) shouldn't leave any permanent marks on your guitar or damage the finish. Simply wipe down the guitar with a warm damp cloth if and when you decided to remove the the unit and you're done .... it's that simple. However, if you should prefer a more permanent mounting by using screws this option is also available to you. All of the components offered in this package are in great shape (as depicted by the photos) and fully functional.

If you’ve been following the price of controllers, and 24-pin cables then you know these controllers can run into the thousands of dollars and the 24-pin cables will cost you between $275-$300. Moreover, you’ll probably end up having purchased a controller that’s pretty much a “one-trick-pony”. In other words it may not sound authentic when not being used as a synth controller. This is the most economical and flexible way to go if you're wanting to get into those vintage synth sounds without selling your grandmother's "Hoveround Scooter". I have a GR-300, and 24-pin cable listed in one of my other auctions (in case you want to verify the price of the 24-pin cable alone). Most controllers as stated above will cost over $1000.00, depending on the model and condition of the controller.

You can connect this unit to a GR-300, GR-100, GM-70, GR-700, MC-1, or even the venerable Korg Z3."
