(interpolated) delay & Envelope?

See the included schematic: Exchange the standard delay component with an interpolated delay component.

Can somebody confirm 'strange' behaviour? (actually, over here the interpolated delay doesn't work at all). 😕

I have it running without problems.

TheAudiophileDutchman ·

Also when you press a key multiple times? (do you still notice the delay?)

Tzarls ·

Nope. I get a delay only on the first note, succesive notes get some sort of fade in. But that happens with both non interpolated and interpolated delay.

I don't think the way the stuff is connected, is right. The envelope module is triggered "automatically" from S|M internals when you press a key. So your envelope gets triggered, before the delayed carrier sound arrives. You should place the delay behind the multiplication of caarrier and envelope. An other option would be to delay the gate signal of the envelope, but then you have to switch the envelope module into the "manual gate" mode.

Thanks a lot for having a look, guys! 🙂 I will look more closely into 'the mechanism behind it all' and then post an improved schematic...

Isnt this because you have the delay in a polystream with an adsr? If you let the Release finish and then press a key it will be delayed but if you then press another or the same key it wont be delayed until the release stage is done?

No improvement yet, as here's an interpolated delay which behaves like an 'echo-simulator': what's going on?

Tzarls ·

I just downloaded ,and at least for me it behaves well - I mean, you play a note, and there`s a delay before the attack.

TheAudiophileDutchman ·

Sure, but releasing a note results in an echo-effect (at least on my PC)...

Tzarls ·

Not here. Maybe it`s because you have two outputs (DS and ASIO)?

TheAudiophileDutchman ·

Hmm, strange: my Asio4all driver for the internal soundcard, running @44.1kHz seems to be okay, while my Audiophile (!) USB 64-bit driver running @96kHz is returning the echo... (other SM-synths are running just fine though) 😕

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
