    Hey all,

    In an attempt to achieve a better Boss OC-2, I created this VST plug-in.
    • It provides a means to adjust what are typically fixed settings - such as:
      The filter cutoff frequencies for both the input keying (adjusting can improve tracking), and
      The generated octave square waves (make it sound like a pure sin, full-square, or anywhere in between).

    • DC offset switch - to help accurately track rectified or offset signals.

    • Want the "synth mod" sound from your hardware OC-2, but don't want to (or know how to) actually modify the pedal? This plug-in can do it.

    • Choose between additive oscillators or a phase-multiplier for another variation in tone.

    • Oscillators can be dynamically controlled via either a gate or an envelope-follower (both keyed from the input signal).
      The phase-multiplier simply flips the phase of the keying signal, thus retaining the original dynamics.

    • It also lets you tap the audio and view your waveforms at any stage, so you can SEE how it works, and adjust settings accordingly.
    While I wouldn't expect this to get as much use as a hardware pedal in gigging or band practice situations, I did try to keep the latency as low as possible. Due to the filtering, it will generate a minimum of about 1,235 samples of delay (28ms or 1/36 of a second at 44.1K), but there is delay compensation for mixdown on hosts that support it.

    I've included some presets that run through the capabilities of the plug-in.

    Let me know what you think! I welcome any critiques / suggestions, and if I feel they're justified and worth my time, I would try to make improvements and re-release. For now, this is free for you TBers, but please don't reshare - just send people to this thread or directly to the link below.

    That looks very cool. Nice choice of extra features.

    Any chance you could compile a Mac version?

    Hi guys, thanks for the interest!

    VST is a Steinberg format of plug-in (stands for Virtual Studio Technology).
    It's a mini program that you can"plug in" or use within a larger host program for recording.
    Alternative formats for plug-ins include DirectX, RTAS, AU (Audio Units), AAX, TDM.

    Unfortunately, the software I used to create this VST cannot compile as other formats, so for the time being I'm stuck with only being able to supply this as a VST or a stand-alone executable, sorry.
  6. What did you use to write it?
  7. That looks nice! Will try it for sure.

    I always wanted to give VST programming a shot. Do you mind if I PM you at some point? Just to get things started...

    Greets and happy new year!

    I made this with SynthMaker. I tried learning coding at one point in the past, but it was wayyyy too complicated and long-term of an exercise just so that I could make little plug-ins and programs for myself and friends. SynthMaker allows you to create without knowing code (though it does have a "code component" that uses its own syntax, which you can use for some real low-level programming/processing - I did have to use this to create the flipper circuit on this plug.)

    I should also add, SynthMaker has been replaced with a new version called FlowStone.

    Walter - if that doesn't negate a desire to contact me re: VST creation, feel free!

    Very nice. It looks beautiful. I'll throw this in my arsenal, you never know!

    How can I put this into the zoom B3?
  12. It is a VST...

    Hi edumamare. Unfortunately, the B3 does not support any 3rd party effects, so you cannot install the OC-D2, nor any other plug-ins.

    This is very cool! Need to figure out a VST setup on my Mac. I'm using MainStage and (I think) it only support AudioUnit.

    You're correct - AU only for that host. If you really want to stick with MainStage, you could try using a wrapper - like FXpansion VST to AudioUnit Adapter

    Alternatively, you could try other hosts, like Audacity (free), Cubase (a light version comes with many interfaces), or Reaper (paid).

    It's a shame it is not mac-friendly

    You sir would be a golden hero...
