    Hello,

    I have been recording drumtracks with SSD4. When i do a drumfill i can hear the drums as they are supposed to sound. However, when playing back, it turns out that drumfills miss random notes. This only happens with fills, not with a regular beat.

    I have compared this to Tracktion4 and there everything is recorded as it is supposed to. T4 is 32-bit with the 32-bit version of SSD4 and i use the 64-bit version of Podium and the 64-bit version of SSD4 so it is a bit tricky to compare.

    Does anyone recognize this behaviour in Podium?

    I used to have problems like that. It stopped when I created the midi tracks first and recorded to them, rather than having Podium create the midi tracks during recording. Doing midi via USB (as opposed to a 5 pin midi connector) also helped.

    Thanks for the tips. But this sounds like a bug to me.

    Bumping this. This is a dealbreaker bug for me. Recording drums has become unreliable now.

    Can you describe your recording setup and how you record the midi notes?

    Sure Fritz.

    I have a Yamaha midikit which i hook up to my computer with a regular midicable. I use the midi- interface on my Wamirack soundcard.

    In Podium i only activate the midi-in of the Wamirack ( i have a fw-interface also but i keep the midi-in from that one disabled).

    When triggering my Ssd4 sampler everything seems to work good. I can hear all the right notes being triggered. However when i record it some random notes are missing. This is most noticeable when i make a drumfill; i can hear the fill as it is supposed to sound but the recording misses random notes. It seems the slower i play the more reliable the recording is and vice versa.

    When i record in Tracktion4 all is recorded well so it seems Podium-related.

    Does the missing notes happen around loop points, or can it happen anytime during a recording?

    Does it happen if you record into a preexisting note sequence event?

    What are the note lengths transmitted by the midikit? I wonder if the problem perhaps is due to overlapping notes.

    It happens during the whole recording.

    It also happens when i record into a preexisting midi-clip.

    The problem is not overlapping notes. The (random) notes are not there in the recorded event, but when i play them realtime they ARE triggered because i can hear them.

    The notelenghts? The first note is always much longer than the following recorded ones. Maybe because the first note is so long it prevents the second note from being recorded. It is peculiar because i have noticed that the second note always falls away

    What I meant was that Podium may skip recording a note if a note-on is received before the note-off of the previous note on the same key. Try toggling the ‘use time stamps from driver’ option in the Audio/MIDI dialog.

    Only the first note when starting recording, or the first note on each key?

    Thanks Fritz,

    First note of each key is always much longer in the recorded event and the played note that comes after the first is missing in the recorded event.

    The use time stamps option makes no difference.

    Is the first recorded note also longer in the other DAWs you tried?

    Is the end-point of the recorded first note perhaps where the second note should start?

    Is there any way you can adjust the duration of the note events on the Yamaha kit? Perhaps there are other setup options in the Yamaha menus that can configure how MIDI notes are transmitted.

    What’s the exact model of your Yamaha kit?

    Answers to your questions:

    Yes, but just a little longer than the second note (215 versus 195 for instance). The first two notes on every key are always joint, connected together. So yes, i think the end-point is the point where the second note should start.

    I don’t know, but i will check the manual. It is a Yamaha DTXpress 3.

    I browsed through the DTXpress 3 manual. There is a setting where you can adjust the gating time between note-on/off messages (section 1-7). Could you try to decrease this interval and see if this reduces the number of missing recorded notes?

    Ah thanks. I will report back.
