When the Memory Writer is in cyclic mode, it seems that it continues to record until the end of the buffer when we switch the trigger to 0. Is there a way to stop recording exactly at that time or, even better, to stop and go when the trigger switch between 0 and 1?

Thanks

You also can use the Waveshaper with recordings from MemoryWriters.

The other application is a bit more simple. I have the memory writer in cyclic mode recording all the time, but at a certain moment of the performance it must stop recording (and exactly at that time), then the Sample player continues to loop with the material that has been recorded until then.

I hope my explanation is clear enough ;-)

Would it be a solution to buy the Looper Construction Kit?

Thanks a lot for your help.

!Gate durationOfGate

which will give you the number of seconds that !Gate was turned on. If you divide this number by the CaptureDuration of the MemoryWriter, this will give you your LoopEnd. Their might be an example of this in the Kyma Sound Library in Sampling/Live Capture and Looping.kym.

I think peteDSPModules (Found on the tweaky) will do what you want. If you use a StepWriter module with an UpDownCounter module feeding its index, you should be able to control it all at sample rate. The logic modules may help with the senceing control if they need to be at sample rate too.

You will need to be logged in before you can get to the link.

You will need both the UserCode.zip and the PetesDSPModules9-12-03.kym to get it working.

I'm eager to try your microsounds. But I couldn't make them running yet as it seems I didn't put the .asy file at the right place (could not find any folder with other .asy files in the Kyma X.app folder). I could open the .kym file though and check the various modules. It looks really exciting, a nice addition to the existing Kyma library. It will also be very usefull for other projects I have in mind. Thanks a lot for sharing this with us!

SSC: I will try with the "durationOfGate" command too. I was thinking to keep the sample length constant but it would be interesting to see what's happening in this case, with the kind of mess around I do then with the sample player. Thanks!

If you are using a mac I think you need to import them first before using them.

Maybe some other kyma users can help out here as I've never had to import them myself.

By the way, is there any "index reader" too. This way of reading the memory might be more efficient than the Sample module for the "pattern playback" algorithm that I'm trying to implement (basically, it is a small loop of a few ms that span slowly through the memory buffer with a few samples increment at each loop).

I've said this a few times before, but the waveshapper module is probably the most badly named module in Kyma. It implies something you use for creating destortion and nothing much else. It is actualy one of the most powerfull modules in Kyma and should realy be called memory reader or random access memory player as that is what it is. What ever you put in it's index input determines what point of sample RAM is outputed. If the index rises towards +1 it plays forward and if the index goes towards -1 it plays backwards. This is the module you need just ignore the name. Maybe I should wrap it in a new class and call it memory reader then it may get the popularity it rightly deservse.

The ramps counters and index manipulators in petes DSPModules are optimised to work with this module and the memory writer in petes DSPModules is it turn optimised to work with them.

I know it's a long time, but I wanted to thank you for the step writer and other modules of your library. They have been extremely useful and I could build the kind of circular buffer I was looking for. However, I'm running now into a problem as I use three different step writers in a patch and this causes the Out of Realtime problem. It seems they are all scheduled on DSP 5 (I have six of them). the other four DSP's are totally empty in the DSP meter but I still get this error. (I have a Capy 320).

Do you have any idea of what I could do?

Thanks again for sharing those modules with the community ;-)

SSC: I will check your version of Pete's modules. Thanks for the link. Hopefully this includes the StepWriter as well. The thread looks very interesting anyway.
