Sounds variation without intention

hi,

what could be responsible for making a sound change with norecognizable reason? i have for example created a basedrum sound where sometimes the sound is not as massive as it is ment to be. for no obvious reasons. there is no lfo involved, no velocity, no pulse modulation and no detune.

are there other parameters to look at? maybe i’ll try to get the sound uploaded, but i have never done before, so i dont know how to get the sound out of my a4 into the computer via sysex.

cheers,
ello

Oscillator drift is on?

How is your drum sound constructed? Eg, using filter resonance, oscillators etc.

i think the answer is here ^ - i noticed the same issue (read elsewhere on here it was due to the filter needing time to build up resonance when self-oscillating)
easiest way to test is to get some boom kicks (self osc) on fours and sound lock in a hi-hat in-between, it destroys the kick level - disconcerting, but just a case of accepting this is a real electrical instrument with nuances !

need to check this. (or first find it :wink:

it makes use of filter resonance and oscilator pitch with an envelope. i’ll try to upload the sound if i manage to get it out of the a4.

avantronica, i noticed the same when trying base and hihat like sounds in one track…

I’ve run into this issue too with bass drums and it is quite annoying. As mentioned, the resonance takes time to build up. So any sounds you have between the bass drum hits will often interfere with the bass drum sounds quite a lot…
Which is a shame because otherwise the A4 is really cool for drum sounds, in my opinion.

I’ve been quietly hoping a firmware tweak may fix it…

At least we got 4 synths in the same box though. So in the worst case, a workaround is to just keep bass drum sounds to their own track.
Or of course sample them and play them from something else.

here is the content of the syx file. maybe someone wants to check why those variations happen:

I see your bytes and advise you to enable TRG on the secondary OSC2 page.

(edit: this looked good at first but then it started to get wonky… dunno, some weird interaction of the OSC with the filter? Got it consistent by setting OSC1 WAV to TRI, TRK OFF, and TUN -32).

:joy:

the re triggering of the oscillator as suggested by void works fine by me, doesn’t get wonky (with or without adding drift) - it’s quite a difference and something worth noting :+1: (make sure underlying fx and perf settings on the track being demoed on are all neutral)

I see a woman in a red dress!! :stuck_out_tongue_winking_eye: :kiss:

cool, thank you :slight_smile:

@poonti: donbt believe her :slight_smile:

take a look at this tutorial :

i make sure to indicate that retrig is on for a solid, consistent kick drum sound :slight_smile:

PLEASE make more tutorials in your A4 series! There’s A LOT of tutorials on YT for Octatrack, but not nearly enough of A4 ones and love your tutorials most. Thanks in advance!!!

Ran into something like this today and glad i managed to pinpoint it so I’m sharing it, even though it may seem obvious to some people:

I noticed using a sound lock with one of my custom bass sounds was causing the transpositioning of that track to go out of wack every time it hit that sound lock trig. Setting the OSC retrig in my bass sound to the right (ON) fixed it.

I wish i could replicate and control this behaviour though, like making a transpose lock trig, to transpose the track in those parts. I know about transpose locking manually (FUNC+Transpose) and transposing in chain mode but thats not quite the same, it’s a bit tedious. Am I missing something ?
