Today I wanted to tackle a long time wish for ableton: A bass-synth that can output a sine wave but always stops exactly after x cycles of the sine wave.

So my plan was to divide a second by the pitch in Hz to get the number of ms for one wave cycle.

Multiply this by the number of desired cycles x and then gate the midi input (or the audio output?) to that exact length and play the note.

If everything is as exact as I hope, I should be able to get a clean sine without clicks in the beginning or end, even though attack and release are basically 0ms.

So far I tried to connect a cycles~ object to an adsr~ object via a multiplication object (*~) , but quickly realized that adsr won't get me far, because I dont want the signal to fade out slowly. 

EDIT: So probably I need to use a gate~ ?

Also cycles~ seems to use a cosine wave instead of a sine wave by default so I always get a click in the beginning. 

EDIT: Probably fixed by using sample-offset?

So anyone got an idea what to use instead? The idea seems like it would be a really simple patch for someone who knows what he's doing, but for me after hours of digging through M4L documentation I'm still stuck at a very clicky bass sound.

Hi guys!

the slope of an audio-rate wave is too steep, you'd hear a click anyway.

it's possible to do this. but to do this right, you'd have to be sample accurate.

maybe by analyzing the number of zero-crossing of the output wave, you could know when to stop it. you can have a look at the zerox example.

you could take a look at the phasor example too, to drive a cycle with phase as the attribute index.

you'd have to add, as you said, an offset of + 0.75

gen~ allows this.

That's exactly what I need right now, the information that it CAN be done, and a direction. I'll experiment with that a bit and report back with the results.

I built the patch with just normal Max using zerox~ to stop the note after x cycles. As Bertrandfraysse predicted, there was still quite a click.

What I got working so far is when I replace the cycle~ with gen~, and inside gen~ I put a "cycle" operator between in and out, everything is as before.

But I assume that the whole testing for intersections with the x-axis (zerox~) has to be done inside the gen~ object to be sample accurate, but there is no such thing as zerox~ inside gen~. 

Also I managed to set the @index of the cycle object inside gen~ to "phase". Then I connected a "phasor" to it, but that just seems to generate a sawtooth of a fixed frequency. I just have no idea how to use that to solve my problem :D

So maybe some hints what to actually do inside gen~?

Thanks for the quick reply!

So now it's time for gen~.
