Sequencer Specifications

Maximum versatility meets real-time control... from your iPad!

The Tetra Midi Analog Performance Sequencer (Tetra MAPS) vastly improves on the first 'MAPS' core design. Expect to use a sequencer that is more versatile and intuitive. Tetra MAPS gives you infinite virtual tracks, modulations and multiple, real-time versions of each sequence, polyphonic sequencing, four channels of CV output, computer network Open Sound Control and over 24,000 notes organized as:

• 16 Sets
• of 24 Bank Tracks
• of 8 Sequences
• of 8 Steps
• of 7 Parameters
• And Multiple Virtual Sequences
• Per-Step Note, Pitch, Velocity, Controller
• Per-Step Duration and Note Duration
• Per-Step Glide/Slew Rate
• Plus a Full-Featured Four Channel Polyphonic MIDI to CV Converter
• And Ethernet Open Sound Control (OSC) Communications

Real-time Interface
Real-time Flexibility

• Continuous turn "encoder" knobs and LCD display for instantaneous access to any parameter
• Display step parameters as bar graphics, octaves, en-harmonics, or numbers
• Perform from the sequencer using its encoder knob buttons to trigger and control sequences
• Perform the sequencer remotely using MIDI or Ethernet Open Sound Control

Some of TETRA MAPS Version 3.2 Features

• Ethernet Open Sound Control (OSC) Networking
• Now communicate with OSC-enabled applications such as MAX/MSP, iPhone/iPad TouchOSC
• Network multiple Tetra MAPS sequencers using Ethernet OSC
• More sequences - over 24,000 note capacity
• New Track View includes:
• volume - mixer like control of sequence volumes
• mute on/off individual sequence tracks
• single knob modulation of sequence tracks
• meta-link - easily links sequences into long tracks
• polyphonic MIDI record
• Sequence track and bank Stop and other short-cut key combinations
• Plus 4 Channels of Control Voltage Output
• Available in multiple rack formats

Sequence Step Matrix
Moves beyond a typical MIDI Sequencer

• Real-time sequence step modes:
note, scale, detune, velocity, controller, step duration, note duration, slew rate
• Step notes are tuneable to 1/64th semitone 'un-quantized' resolution
• Force step note to one of 50 musical scales
• Per-step glide or slew rate for MIDI pitch-bend slew or portamento output
• Sequence Loop and Link for long patterns up to 1536 steps
and multiple instances thereof
• Multiple sequence track modulation sources:
A sequence or other source may modulate sequence pitch, velocity, controller, event times and more
Track modulation allows global and recursive sequence modulation
• Random step advance and pendulum modes
• Real-time control of MIDI program numbers
• Per-bank and global BPM tempos
• Ethernet input and output, 32 channel MIDI output
• Control Voltage modulation input for sequence transposition, step time and more

Variable Event Times and Durations
Moves beyond the traditional Step Sequencer

• Per-step step and note durations:
Note off, skip step to 64th, dotted, whole note and triplet durations
• Over 24,000 note memory
• Polyphonic MIDI record
• Ability to create polyphonic and monophonic sequence combinations
• Sync triggers to beat or free-time, independent to each sequence
• Sync sequence loop to bar length, independent to each sequence
• Cross-rhythms are easily generated with Bar Sync
• Step fractional time-shift modulation via sequence modulator inputs
• Programable external clock sources and timing resolution

Dynamic Sequence Triggering
Makes this the Performance Sequencer

• Concurrent triggering of each bank group of 8 sequences,
with multiple virtual sequence iterations
• Meta trigger sequences with the single turn of an encoder knob
• Sequencer trigger sources:
Sequences are knob button assignable and MIDI channel or note assignable
Sequence iterations track MIDI trigger note, velocity, note duration, and note instances
• Global sequence track modulation
• Sequence cross-modulation
• Triggers sync to beat or free-time; create MIDI echo
• Sequencer trigger modes:

Multiple                 sequences follow all trigger instances
Multiple Arp           multiple sequence note trigger taken as an arpeggiated note
Single                   sequence follows monophonic trigger
Duration Follow      sequence note duration follows trigger duration
Loop Hold             sequence loops while trigger is held
Run/Stop               trigger play; trigger stop
Run/Stop Arp         run/stop sequence note trigger taken as an arpeggiated note
Seq Reset             trigger play; trigger reset sequence
Release                trigger sequence_n; sequence_n+1 on trigger release
Step Play              trigger plays the next successive step
Step Record           trigger sets step value
Step Randomize     trigger sets random step values
