"The Yamaha DX-21 FM digital synth makes for a stellar, retro-synth performance piece, as well as a groovin' vintage(ish) practice/jam unit. This synth is the most versatile of the 4-operator family of Yamaha's DX synth line [edit: or the DX11? You can find the user manuals here: http://www.yamaha.co.jp/manual/english/ and compare]. The keyboard isn't touch sensitive, but the sounds can have velocity values if played from a touch-sensitive keyboard. If you spend the time, you can come up with some pretty interesting digital synths and effects if you are wiling to push some buttons and experiment with the programming. Layering the same sound with itself and increasing the dual detune value can make the DX21 sound much fatter than the DX7 for synth, string, and pad sounds. The split function is variable and can be quite useful for performers.

Features
This synth board features a 32 Performance Memory System, programmable with data on play modes, key shift, detune and pitch bend. It will automatically recall these real-time performance parameters as well as the voice or combination of voices. Instead of VCOs, VCAs, and VCFs, the DX21 uses "operators" (a digital sine wave generator combined with an envelope generator) to produce sound that can be used alone or in combination with other operators. It has 32 RAM (Random Access Memory) voice memories, organized in two banks of 16 voice selector keys. There are 128 pre-programmed voices permanently stored in internal ROM (Read Only) memory. Organized into groups of 8, these voices can be loaded individually or in groups into the 32-voice RAM memory. Two FM Tone Generators allow voices to be selected three ways: Single, Dual, or Split play modes. A broad range of MIDI functions make the DX21 exceptionally useful in virtually any MIDI system application. A built in cassette interface allows an unlimited number of voices to be programmed and stored on cassette tape. Cassette voices can then be loaded into RAM memory when needed.

Analogue Solutions Leipzig-SK

Noisebug (RSS)

"Manufacturer Description [analoguesolutions.org.uk]:
Analogue monosynth with analogue sequencer / keyboard

KEY FEATURES OF LEIPZIG-SK:
Pure analogue voice and modulation circuitry.
Fat Moog style transistor ladder filter.
2 VCOs with Glide and Sub-VCOs.
Osc Sync & Cross-Mod
Plenty of modulation routing possibilities.
We are a big fan of electronic percussion here, so Leipzig-S modulation choices provide for good drum possibilities
Analogue step sequencer – with plenty of clocking options.
Audio input so can be used as a sound processor.
Rugged steel/aluminum construction.
MIDI In for software sequencer control.

This synth has NO memories! - Advantages;
None of the parameters or controls are quantized. So when you turn a knob, you are turning a resistor that affects a real analogue circuits.
Because each parameter is not under solid CPU control, each parameter has that tiny analogue drift that adds so much to character.
You are forces to be creative. No reliance on presets! Each time you make a sound you are being original.
Quick, easy and simple to use! WYSIWYG - no nasty menus and sub-menus to change the sound.

The SK is almost identical to the S. But with the addition of a MIDI controller keyboard.

Keyboard:
Velocity sensitive, semi-weighted, 37 keys
LCD to enable editing of keyboard set-up (transpose, pitch bend range, retrig, etc)
1/4" CV inputs and outputs
Headphone socket
Internal power supply
Pitch and Mod wheels

Differences between Leipzig-S/SK and the original Leipzig;
Envelopes are now full ADSR
EGs can be disconnected from MIDI trigger
VCO2 can be disconnected from MIDI (free running modulator!)
Analogue step sequencer
VCF can be modulated from either EG1 or EG2"

Ensoniq Mirage DSK with 22 extra disks

via this auction

"The Mirage was an 8-bit sampler capable of a maximum sampling-rate of 32kHz with a limited 128Kb of RAM. Those are pretty old-school specs by today's standards and while it does mean your sounds will be somewhat lo-fi, that does not mean low quality. A built-in 3.5 inch DD disk drive was used to load and store samples, sequences - even the operating system. Each disk could hold up to 6 samples and 8 sequences. The keyboard is split in to two independent halves for an upper sound and a lower sound - great for playing two instruments at a time. Unfortunately, sample editing is done via hexadecimal-code manipulation which is not a simple to concept to master. Most users will just load-in sounds from the Mirage's extensive sample library, or look for computer programs that can edit or convert Mirage samples.

While the Mirage's limited sampling specs, limited polyphony (8 voices) and limited sequencer (333 notes) may seem to knock it off anyone's list when looking for a keyboard sampler, the Mirage still has a few hidden goodies under its hood. Most notably, it has analog filters...a true, analog VCF with low-pass filtering and keyboard tracking. In addition to that it has five-stage envelopes for the VCA and VCF and a nice LFO. Most models also featured a weighted, velocity sensitive keyboard."

Noisebug (RSS)

"The Tom Oberheim Synthesizer Expander Module Pro version, (SEM-PRO), incorporates twenty-one minijacks for signal access to the primary patchpoints in the sonic flow along with the MIDI-to-CV converter.

Each of the SEM-PRO instruments will be personally signed by Tom Oberheim.

Specifications:
SEM with MIDI to CV Converter and integrated patch panel. This version of the SEM combines the features of the MIDI to CV version with a 21-jack CV patch panel and is personally autographed by Tom Oberheim. 21 SEM connections are brought out to 3.5mm minijacks. The basic connections are a one-volt-per-octave VCO control voltage and a standard 0 to +5 volt gate signal.

This version includes a high precision MIDI to CV Converter that has been specifically designed to allow MIDI to control the SEM, and has additional features that make use of the SEM's external inputs. Some of the features of the MIDI to CV Converter are:

* Select MIDI channel, controller number and bend range
* Select note assignment modes: latest, high note and low note priorities
* Select note re-trigger, filter track, LFO reset
* A second independent control bus allows velocity, controller data, or channel pressure to modulate either or both VCOs, the filter and the VCA
* Transpose function allows different keyboard controllers to utilize the complete MIDI note range
* Analog portamento
* Input preamp gain control - allows an external audio input to be processed thru the SEM
* High precision A-440 Hz tune signal
* Control voltages and gate are bought out to rear panel connectors so MIDI to CV function can be used with other CV/Gate gear."

Spooky Sequencer

YouTube Published on Jun 12, 2012 by hotchk155

"I'm experimenting with different sequencer approaches on the Launchpad. The code is running on a DIY microcontroller board, turning the Launchpad into a standalone MIDI hardware sequencer.

In this clip the top 6 rows of the Launchpad grid are mapped to MIDI notes (counting along and upwards from note C3). When the step counter in the lower 2 rows hits a green square it plays the next green note selected in the grid, same goes for red notes.

A yellow square in the step counter plays next red and green notes together. A yellow note in the grid behaves like both a red and green. The result is two cycling note lines that fall in and out of synch with each other depending on how many notes are selected of each colour. It comes out kind of hypnotic and spooky - not really what I was originally going for, but I ran with it anyway.

The hardware is an FTDI VNC2 chip on a DIY board. I am fighting with the buggy IDE and compiler to try to get a useful standalone hard sequencer/control surface from the Launchpad."
