midiFILTr-PG Probability Gate MIDI Filter Effect for iOS

Published on Apr 23, 2017 Art Kerns Music + Apps

"This is a demo of the midiFILTr-PG probability gate MIDI effect for iOS. Use with Audiobus 3 or configure manually with CoreMIDI. Works on both iPhone and iPad, available now in the app store"

iTunes: midiFILTr-PG Probability Gate MIDI Effect - Arthur Kerns

"midiFILTr-PG is a Probability Gate MIDI effect designed for Audiobus 3 but also usable with CoreMIDI. midiFILTr-PG listens to MIDI input and based on random chance mutes some of the incoming notes to make a busy, repetitive stream of notes a little more interesting and sparser. It has four modes:

Gate Mode - One set percentage to be muted for all notes. Also includes Gate On Repeats (when a note passes through unmuted, also pass through X more notes after) and Gate Off Repeats (when a note does not pass through the gate, also mute the next X notes) to make things a little more interesting.

Note Mode - Each note in the scale (C, C#, D etc) has its own percentage chance to mute incoming notes.

Sequencer Mode - Every eight notes has a different percentage chance to be muted. Can also change the sequence length to be less than eight.

Thru Mode - Nothing is muted, normally not used but there if you need it.

If midiFILTr-PG is inserted as an Audiobus 3 MIDI effect it should be setup and work automatically. If you wish to use it without Audiobus you can toggle the CoreMIDI input and output and use it that way."

Re-Badged Rheem Kee Bass NDK Kee Boo Vintage 60's Analog Bass Synth / Organ

Note this is the first time, this specific model has been featured here on MATRIXSYNTH. Curious bit of synth history. There have only been two other NDK posts before this.

"Rare NDK 'Kee Boo' a variant of the Rheem Kee Bass Analog Bass Organ. Both share an identical circuit, only differences are the Black Sparkle opposed to Red Swirl and Boost knob instead of slider. This Kee Bass was recently serviced and had new precision locking tuning pots installed as some of the original pots had become faulty. The original power cord pocket shows No signs of damage, and the original power cord has had some hot glue added to reinforce the joints against pulling wear. The Tolex is in great shape. The plastic red jewel that cover the bulb is broken. The bulb itself is fine though. The chrome bulb surround is included along with the NDK badge that was originally glued over the words "Kee Bass" on the rear plate. Ready to play for many years to come! Extremely low sub bass, fantastic for Dub and electronic."

MPC ELECTRONICS MPC-1 MUSIC PERCUSSION COMPUTER

via this auction

"Superb analogue drum machine dating from c1983. In excellent condition and working order following an extensive professional service.

These are uncommon in any condition, but this only the second example we've seen that works as it should. It's a ground-breaking historic analogue drum synth with onboard sequencer, designed to link up with either a Sinclair ZX81 (UK) or Timex 1000 (USA) personal computer to provide computer-programmed beats for the first time ever.

This example is in excellent condition - it has a few minor scuffs and dings as you would expect but it is looking great for its age.

Functionally it's in great working condition and it's wonderful to finally be able to program one of these machines - we've had several over the years, but most fail to retain programmed sequences for more than a bar or two before crashing. We must add the caveat that as this machine is based on ancient computer technology, we can only offer limited guarantees as to its future operating state: it works now, but we can't offer any extended warranty beyond a guarantee that it will arrive in working order: if there is any problem at all on delivery, please email us immediately.

Capable of a range of quality analogue drum synth sounds and, being one of the less-common and seldom-used drum synths, it immediately has an appeal if you're looking to stand out from the crowd.

This English drum synth/computer, designed in 1981 by Clive Button and launched to great acclaim a year or so later, was revolutionary but alas very short-lived; there are few surviving examples to be found in any state, let alone good working order. Originally used by Depeche Mode, the MPC-1 failed to replicate their successes and hit the big time and sank without trace, unlike its later namesake - Roger Linn's famed MPC series (no connection). It has an 8 bit processor and a massive 4kb of onboard memory to store programmed beats - these can be loaded/dumped via the tape in/out interface (not tested).
