The 512 provides 9 octave ranges for the 29 full-sized keys (although shorter in length than typical keys) with response to Velocity and Aftertouch. Users can define one of five different Velocity and Aftertouch curves to apply to the keyboard, and dial in the range for each curve to customize the response. The Pitch Bend provides positive and negative pitch bends, and the bend range can be adjusted for full or half range. Mod Wheel is also provided as a modulation source.
The arpeggiator allows you to quickly construct melodies on the fly, and manipulate them to your hearts content. Up to 16 notes can arpeggiate, and there are 29 user definable rhythm patterns to apply to an arpeggiation. Each step of a rhythm pattern can define note on/off, note duration, sustain, glide, and velocity value. Rhythm patterns can be reassigned to an arpeggiation on the fly. Arpeggiations can play in five directions being: Up, Down, Up/Down (inclusive or exclusive), and Random. You can also apply up to +/- 4 octave reiterations so the arpeggiation plays through multiple octave ranges automatically.
When notes are entered live into the arpeggiator the 512 will generate the typical ascending playback order (when playing in the UP direction), or descending (when playing in the Down direction). At any time you can latch the held notes into memory using the Hold feature. Once Hold mode is active, you can enter notes in any order, and even use the same pitch multiple times.
Once the arpeggiation is latched with the Hold feature the real fun begins. You are free to select different scales, add chords, apply chord inversion, transpose, scalar transpose, change octaves, rhythm patterns, note combinations, MIDI channels, or time signatures. You can also add Pitch Bend, Mod Wheel, and Aftertouch control, and all of these can be done in realtime.
The 512 sequencer is similar to beloved classics like the SH-101 or Pro-one in how easy it is to use them. However the 512’s sequencer expands on these ideas and goes a lot further. There are 145 user writable sequencer pattern locations. Each pattern can be any length up to 64 steps (4 bars when using 4/4 time signature). Each step records a single note pitch, the note duration, sustain, glide, and velocity. Similar to the arpeggiator, the sequencer in the 512 can play sequences in five directions being Forwards, Backwards, Fowards/Backwards (inclusive and exclusive), and Random. And again, you can apply up to +/- 4 octave reiterations so the sequence plays through multiple octave ranges automatically.
Once a sequence is playing, you are free to select different sequences to play next, choose different scales, add chords, apply chord inversion, transpose, scalar transpose, change octaves, MIDI channels, or time signatures on the fly. You can also add Pitch Bend, Mod Wheel, and Aftertouch control in realtime.
MIDI TO CV CONVERSION
The 512 allows you to convert MIDI information such as Note On/Off, Pitch, Pitch Bend, Mod Wheel, Velocity, Aftertouch, and Clock to CV/Gate signals for controlling your favorite analog synthesizers. While there are many MIDI to CV converters on the market, the 512 has some really useful features that set it apart from the rest. For instance, if your MIDI source (sequencer) is not providing things like Pitch Bend, Mod Wheel, or Aftertouch you can generate these controls live from the 512’s touch surfaces to add additional control over your synthesizer in realtime. You can force incoming MIDI notes to specific scales, or transpose incoming pitches using octave, linear, or scalar transpositions all in realtime. You can also define the sync rate of the analog clock vs. the MIDI clock, or add shuffle to the analog clock.
MIDI TO MIDI CONVERSION
The 512 allows you to manipulate and add to any existing MIDI information. For instance, if your MIDI source (external sequencer) is not providing things like Pitch Bend, Mod Wheel, or Aftertouch you can generate these controls live from the 512’s touch surfaces to add additional control to your MIDI sound module in realtime. You can even force incoming MIDI notes to specific scales, capture scales via external MIDI notes, transpose incoming pitches using octave, linear, or scalar transpositions, or apply chords to incoming notes. Best of all, it can be done on the fly!
Want more? Check out the 512’s Poly MIDI modes, where notes played on the keyboard or MIDI notes received from external devices can be intelligently rerouted to different MIDI channels so that you can play up to 16 monophonic synthesizers polyphonically via MIDI. This works with Note On/Off, Pitch, Pitch Bend, Mod Wheel, Velocity, and Aftertouch. Even if you do not have multiple monosynths, this feature creates some really unique results when controlling multitimbral MIDI sound modules too!
The 512 provides 28 user writable scales plus the chromatic scale. These scales can be applied to the keyboard, arpeggiator, sequencer or while doing MIDI to CV and MIDI converstion. Each scale can contain up to 29 notes in any order allowing you to achieve both traditional and new experimental forms of music generation. Scale notes can be mapped to the keyboard in one of two ways (full or partial), and you can invert the keyboard scale as well.
When using external sequencers and running MIDI through the 512 as a MIDI to MIDI conversion, you can capture the MIDI notes received from the external sequencer and create a custom scale based on these notes. Furthermore you can then do cool things like apply scalar transposition to external sequences, Or capture a scale based on one sequence, then apply it to any other sequence you like.
Remember the old days when you could latch a chord of notes into a keyboard and play it up and down the keyboard using just one finger? The 512 expands this idea further by providing 28 user writable chord locations. Each chord can store/play up to 6 notes. And instead of being able to play only 1 transposition of this chord, the 512 allows you to play up to 16 transpositions of the chord simultaneously. These chords can be applied to the keyboard, arpeggiator, sequencer, or while doing MIDI to MIDI conversion. In addition, you can change chord selections, and apply up to +/- 4 step chord inversions on the fly.
The 512 provides three forms of transpostion, and all can be changed in realtime and be applied simultaneously to the keyboard, arpeggiator, sequencer, or while doing MIDI to CV and MIDI conversion.
The first form of transpose is the 9 octave selector. This allows you to transpose notes in octave values.
The second form of transpose is linear transposition. This is your typical +/- semitone offset found on traditional keyboards. The 512 allows you to linearly transpose notes -12 semitones to +16 semitones steps simply by playing a notes on the keyboard.
The third form of transpose is scalar transposition. This is the most musical form of transposition as it shift notes up and down the currently selected scale only. Therefore all notes, although transposed, still remain within the defined notes of the scale.
Why of course even MIDI is unique in the 512. The 512 allows you to change the MIDI OUT channel on the fly, turning something as simple as the MIDI channel into a performance feature. This can be used to great effect when creating counterpoint music, or when you want a simple melody to sound like a full orchestra.
The 512 can also act as a master or slave clock. Allowing you to control the playback of other devices or sync playback of the arpeggiator and sequencer with external sequencers.
And in this day and age it is important to note that MIDI is provided on standard 5-pin Din jacks. No wonky breakout cables, or non-MIDI standard jacks to worry about here.
The 512 incorperates an autoglide circuit for slewing the Key CV from one pitch to another. This allows notes to glide only when certain conditions are met such as two notes playing simultaneously, or when programmed to do so in the arpeggiator or sequencer patterns. A Glide time control is also provided to determine the rate of the glide effect.
Swing can be applied to the timing of the arpeggiator, sequencer, or analog clock output. This adds a human shuffle feel to the rhythm. The Swing control varies the amount in realtime from 50% to 75%.
Many parameters of the 512 can be customized by the user and stored as a power-up default to be recalled each time the unit is turned on. These include keyboard Velocity curves and ranges, Aftertouch curves and ranges, MIDI aftertouch transmission off/on, Pitch Bend range, Pitch Bend and Mod Wheel response times, default scale, etc.
All user preferences, arpeggiator rhythm patterns, sequences, user scales, and user chords are stored in EEPROM memory. Data written to this memory can be retained for 100+ years with no backup battery to worry about.
A 15V DC universal power supply is provided with each unit. This universal power supply can operate in any country around the world.
