Sequentix P3 Midi Sequencer

via this auction
From the manual:
"The P3 Sequencer is a modern take on the analogue sequencer, but it takes the concept much further P3 is a pattern-based, 8 track hardware MIDI sequencer. Its user interface and primary method of pattern entry are based directly on the classic analogue sequencers. But it adds full storage and recall of patterns, can simultaneously drive multiple MIDI synths or samplers each playing different patterns, allows chaining of patterns to make longer musical phrases than the basic 16 steps, and also features sophisticated pattern modulation options.

In addition, it allows real-time capture of note input from a MIDI keyboard, so you can use P3 like a more typical hardware MIDI sequencer if you want.

P3 allows real-time control of track mutes and simple pattern and pattern chain selection across multiple tracks, plus analogue style editing of patterns with separate note, velocity, tie, gate, length, gate delay, and a combination of up to four MIDI controllers, extra notes, or programmatic functions, per step.

The unique programmatic functions, called auxiliary events, allow the simple creation of patterns that can dynamically grab values from the patterns on other tracks, randomize step values, alter pattern and global settings, and more - including modulation accumulators that can be configured as LFOs, perform arpeggiation effects or enable complex self-modifying patterns.

A non-destructive Force-to-Scale function provides preset and user-defined scales to keep everything in key (but defeat-able per pattern step if required), and a special pattern sync option allows patterns with different lengths and/or timebases to free-run, or be synced to a global bar.

Building on ideas from various vintage and modern analogue sequencers and drum machines, P3 has been designed to provide a direct and intuitive method for creating pattern-based electronic music. That's not to say it will automatically do it all for you - there is a learning curve involved. To get the best from P3 you will need to familiarise yourself with the various modes of operation, pattern and playlist values, track and configuration settings."
