In reply to Steve. Hi, Steve. It sounds different because PD is playing back the sample at a different speed based on the MIDI note; not to mention the fact that you may be playing back only a portion of the full sample (depending on how you set things up). This patch is really designed for mangling your source sound. To play it back in the way you're thinking would require a far more complicated patch than this tutorial is designed to be.

Hey! Awesome tutorial so far, and it looks like the best stuff is still coming in the next couple sections (I read ahead a bit). I’m pretty new to synthesis in general and definitely PD, but I at least seem to be making head way on the PD part. I have some samples that I’ve been loading into the synth and they seem to sound OK when I bang [tabplay~ file], but when I input from my midi device (simple keyboard), the sound doesn’t seem to be the same. Do you know why this is? My first guess was I messed something up when creating a sample, but the graphs seem to be close to identical.

I covered the head/tail smoothing in Part 3 of this series of articles (https://designingsound.org/2013/04/pure-data-wavetable-synth-part-3/). If that post doesn’t answer your question, let me know.

Hi, nice post. I’m just wondering if you can tell me how you did the head-tail smoothing. in your first image I saw that you are sending that variable.
I created a looper in PD using tabwrite~, tabread4~ and phasor~ but it’s becoming hard to create an envelope to smooth the beginning and end of the loop because I don’t have any way to synchronise the “smoother” with the phasor~. There is no way to tell whe phasor~ output is 0. It would be great if you can give me a hand with that. Thanks!!!

Just to confirm…you have two number boxes to feed each of the inputs on [poly 8 1], yes? Have you opened the properties of each number box to change the upper limit to 127? Try this. change the 8 in [poly 8 1] to a 1…so that you now have [poly 1 1]. That will ensure that you’re always using the same voice. Also remember that the “hot inlet” receives the “bang”. Try setting the volume first (number atom feeding the cold inlet), then setting the MIDI note (number feeding the hot inlet). No volume changes will occur if you haven’t changed the “note” value after the volume. you can fix this by adding a [bang] that connects to the inlet of your “note” value number atom. Then you can change the volume and click on the [bang] to update the signal without actually changing the note value.

Let me know if this solves the problem for you.

Hi, I’ve followed your tutorial from start to here but I can’t hear the wavetable. Can hear the file playback fine and everything looks like it should be working. I don’t have a midi controller so followed the last step as well, but still getting nothing. Any suggestions?
