Waveform recording missing audio

[LB92]

Hi all,

Wonder if you can help, new to music/DAW's/electronic instruments.

I have an electric drumkit I'm trying to record, I'm setup connected to the PC via USB and on Waveform with BFD as a plugin. Each hit of my drum has a sound as I play it and registers on Waveform as well.

When I play a recording back, only a single or sometimes none of the hits have any audio. Screenshot below shows an example recording with multiple hits on the same drum but only the final hit is audible in the recording. Can anyone help?


Thanks!

Its probably that your drumkit has different midi note mapping than what your drum software takes by default. You'd need to either go into your drum software and change the individiual drum midi note maps or find a midi effect that can do note remapping and put it before the drum plugin.

Thanks for the fast reply! The drum software seems to work, every drum I hit gives me the right sound out of it.

In waveform, when I did the test in the screenshot it the same drum hit each time. So if it was a mapping issue I'd assume that single drum would never be audible? But its sporadic, some register, most don't. And thats the same across each drum I test, it clearly shows it registered the input, but won't always play a sound for it in the recording. (When being played however they all have sounds).

Might be some timing issues with the electric drumkit. I seem to remember some of them had odd things in the MIDI data stream, that effectively resulted in a note duration of 0, or a velocity so low it was below the threshold; so depending on the VST processing it, might result in the notes being "silenced" before they get a chance to sound.

Check the notes in the MIDI editor to see that; or have a look at MIDI Monitor to see what the note events effectively look like.

BFD definitely uses some interesting drum mapping choices, and I recall they even have a built-in mapping tool to help you convert.

However, you're not importing MIDI drum tracks in from other sources, and are creating your own from a kit, so you definitely shouldn't be seeing this problem (especially if you're not hearing an issue individually). I'm guessing Peter is looking in the right direction for you.
