    Re: blit oscillators not being good for FM...
    I think if you are doing FM and you don't want aliasing, you are going to have to upsample and filter anyway, so you may as well start with mathematically perfect waveforms and at least know what results to expect.
    Anyway a bit of aliasing is nice on FM isn't it? The sound of Yamaha :)

    Thanks. I will probably end up using them or creb. But I would love to figure out a way in PD vanilla without externals. I think I have almost got an anti-aliased triangle wave working without upsampling or filtering.

    @bocanegra - oh yes I remember now. You are right, they are both using similar techniques. The Heavy one is better because it has PWM, I think.

    @seb-harmonik- I will check the link but I don't think I am going to understand it :)

    @oid - yes that won't work with BLEPped or bandlimited wavetables. fine for a naive triangle if you don't mind aliasing.

    @bocanegra - thanks, I will check out your patch. I am using the PWM & sawtooth from the Heavy library, here:

    Yes creating your synced oscillators at a high sample rate, filtering and then downsampling works but it's very processor intensive. I can find some much more efficient implementations in C++ but can't see a way to implement them in pure data.

    Has anyone managed to implement a polyBLEP or similar oscillator with sync in PD? I have a good saw osc & a good PWM but I can't figure out sync.

    Also can't figure out triangles. I suppose I can just filter a square but trying to avoid lots of upsampling & filtering.

    I'm making a fairly complex polysynth that has lots of aliasing so I am upsampling where necessary (complex waves, FM, wavefolding etc) and then filtering.
    The butterworth filter from J07.oversampling uses a lot of CPU and I want to keep my polyphony!
    4 x lop~ chained one after the other uses a lot less but sounds a bit worse.

    What filter are you using for this?

    Hmm maybe I need to give up on Processing/puredatap5 and move over to Java or something else. It seems pretty much unsupported and not updated for a long time.

    Is it possible? I have downloaded the expr dll file but I don't know how to get it to work with libpd.
    Very new to libpd and any other kind of coding apart from PD.
    I am using Processing which is more or less like Java.

    I have a PD synth that I play with an external MIDI keyboard. I want to use libpd so I can make a nicer interface.
    My problem is getting libpd to recognise any incoming MIDI. I've read conflicting stuff around the net like "libpd doesn't support MIDI" or "libpd supports only MIDIIN" etc.
    I don't need to send MIDI from libpd to anywhere else, just need it to notice incoming MIDI. Can anyone help?
    I have used a message of the form [;pd midi-dialog .........[ to make sure the correct MIDI interface is set up. It works in regular PD but not in libpd.
    Specifically I am using puredatap5, the libpd library for Processing.
