Sustain pedal

The sustain pedal is not working with built in instruments but it

is with Auv instruments…I’m on the most resent iOS & Drambo versions…is it just me or is anyone else having the same issue….


  • @giku This appears to be an oversight. It could be handled by some logic, but it really needs to be before the voice assignment, i.e. in MIDI to CV, since sustained notes need to hold their voices until released. Using logic to keep the gate open would not retain the voice.

    Yes Drambo passes sustain messages but MIDI2CV doesn't handle it yet. It's in the works.

    Next update

  • Until we have the full implementation, you could use the attached SustainPedal StreamByter script. Unzip it, copy/paste the text into a StreamByter window and Install Rules. You'll need to route the MIDI through StreamByter in AUM, or use StreamByter as a MIDI effect in Drambo, connected between the track MIDI input and the MIDI2CV, as shown. Please ignore the rest of this pic, but be sure to connect the MIDI2CV to StreamByter and not to the MIDI input.

  • ok ...i think I'll just wait for the next update.....I'm very new to Drambo so wasn't quite sure if this was meant to work.... but i am loving exploring the modular world....what a wonderful thing is Drambo....

  • Excited for this.

  • I’m excited for this as well! Does this also mean that we’ll be able to record sustain pedal messages into the sequencer? So far I haven’t been able to get this working without complicated workarounds or additional Mozaic scripts (best result so far is using a cc modulator to record as automation - but it’s not working reliably). As a piano player, being able to record performances with the sustain pedal would be a HUGE deal for me.

    (also thank you - Drambo is ridiculously incredible)

  • I've just tried this script and it works really well.

    I don't have a sustain pedal so I've mapped it to a pad and it works wonders.

    Going to try it with the ARP module next.

    Thank you very much.

  • This is good to hear, thank you.

    Actually, you only need the StreamByter Audio Unit MIDI Processor (MIDI Effect), not the StreamByter (Instrument), although I'm not sure what the difference is.

    Bump, is this still in the works for an update? Would be extremely helpful for me. Thanks!

  • Hey guys! I would like to be able to record some performances playing virtual pianos and this functionality would be very important. Is there anything new about this native implementation of recognizing MIDI information sent by the sustain pedal?

  • Hi.

    Sustain pedal drama

    Is this something thats fixable now or in ongoing works.

    Its a cc ( not 64 ) sent out via blueboard ( A continous pedal )

    When you map more than 1 instance.

    You get some non audio clipping.

    At .42 etc

  • @sigma79 So which CC are you talking about of it's not 64?

    If by audio clipping you mean the audible clicks while turning the Sustain knob in your video, are you sure it's not coming from the Pianoteq plugin itself?

  • Hi rs2000.

    It dosent happen in aum ( which I cant use )

    It will happen with any app in Drambo.

    Having cc 13 midi ch 1

    Sustain pedal routed through blueboard.

    Anything more than 1 mapping.

  • Obviously you can map a controller knob as cc13 midi ch 1 ( from an ec4 )

    No issue.

    Its just when sent via bt, blueboard and sustain pedal.

    but dosent happen in aum.

  • lol

    Its maybe the buffer.

    These apps are heavy cpu.

  • Issue isnt resolved.

    Unless buffer size is way worse to use, than aum?

    Its a sustain ( on ch 1, cc 12 ) through a blueboard.

    Its a scratchy glitch

    and its the same scratchy glitch as when trying to use bleass voices in drambo. Trying to sequence the harmonic voices via drambo sequencer cause the same. Drambo also runs out of stereo tracks for bleass multiouts ( after 8 is mono ) Perhaps because drambo used to be 8 tracks.

    The bleass thing just complicates question ( the sustain glitches ) but is same noise.
