    Description

    This is a newly developed (modern) replacement CPU for the
    Sequential Circuits Pro One
    8021. Bring that old Pro One back to life or simply have a spare for the "unobtanium" 8021.
    Turbo CPU Features:
    Plug n Play.
    Non-destructive FLAT pins. I don't use square pins that destroy the CPU socket.
    Supports the original functionality including the sequencer and arpeggiator.
    Each sequence can be up to 256 steps (compared to total of 40 steps on the original).
    Sequences are retained in memory even after power-down. The CPU module does not use a battery.
    Power-on settable parameters for clock start mode, arpeggio up/down mode and arpeggio gate time.
    Sequence Tie mode allows for a variety of note lengths.
    Sequence End mode lets you "chain" the two sequences.
    Plus a MIDI In/Out interface board
    that adds the following features:
    Firmware update (“re-flashing”) over MIDI (using my application or MIDIOX or similar).
    Settable MIDI channel.
    Monophonic MIDI output of arpeggiator and sequencer data.
    Monophonc MIDI in of keyboard data.
    Polyphonic MIDI output of keyboard data.
    Arpeggiator and sequencer sync-able to MIDI Sync In (settable clock rate).
    Load/Save sequence data over MIDI.
    MIDI In, MIDI Out and optional MIDI Thru.
    Optional MIDI In/Out activity LEDs.
    Soldering and installation are required for MIDI.

    A Note about the preliminary CV option:
    If you are interested in the extra DAC board add-on ("CPU+MIDI+CV" which provides among other things LFO2, Pitch bend receive and controllable Cutoff and Resonance over MIDI), send me a message.  There are 2 ways to go... I can solder the chip/board on and test for a nominal charge () or you can obtain one and solder it yourself.  See the web page (link at bottom) for more about this. Here is the installation info:
