    This looks interesting mark, I think i saw some of this in paul's code for waveformMod, it really looks like something useful to learn. I will look into this and also the arm special instructions...

    Yeah the interpolated number does end up as an integer. I just don't know where to really start converting it all into integer math, because the interpolation is modular but the multiplier for the...
  3. Using integer math instead of floating point?

    I'm using floating point math for interpolation through a wavetable, but it seems quite inefficient and requires converting ints to floats and vice versa.
    Is there a way to convert my code to work...
  4. I have managed to modify the waveform object to...

    I have managed to modify the waveform object to work with wavetables - the only current problem is that the interpolation all uses floats, and the audio stream inputs are 16 bit ints.

    case...
  5. I was doing the crossfading before and it worked...

    I was doing the crossfading before and it worked well, I was just looking really for a way to modulate the table position using LFOs and envelopes. I was hoping to get the shape input to work as...
  6. Large wavetables using waveform object.

    I have managed to create wavetables containing ~5 waves by assigning them to seperate waveform objects and then fading between them. However this is starting to get quite CPU intensive for more...

    I'm quite new to c++, so I dont fully understand a lot of the code in waveformMod. I can't see a simple variable for the unmodulated phase, the only thing i was really able to identify was phasedata,...

    I dont think so, because phaseModulation is relative to the current phase I can't see a way of it being useful for setting an absolute phase value without knowing the current phase. Also, I am using...

    Settings waveform modulated phase.

    I am trying to implement oscillator sync into my synth. The waveform class supports the phase(angle) function which would have been pretty essential but the waveformMod class doesn't seem to. Is...

    I would have the waveform object have an amplitude of 1. Have the lfo have an amplitude of 0.1 and an offset of 0.7. Use the multiply object (in the effects section) to multiply the 2 together....

    The code in waveform modulated is way beyond me :), i will try figure out what is actually going on before trying to implement a different kind of FM. Do you know what rshift and rshift rounded are?

    Question about waveform modulated.

    I have noticed that waveform modulated uses exponential FM, however i am interested in achieving linear FM. Is there a way to either modify the waveform modulated object to support linear FM, or to...
  14. How to achieve linear FM with waveform modulated?

    I'm looking into creating an FM synth and have noticed that, while most FM synths use linear FM, the waveform modulated object uses exponential. Would there be a way of modifying the waveform...

    For the size of the samples, anything 10 seconds + would be great. As for the teensy, i have a 4 on hand, but i wouldn't mind using a 4.1 if it allowed for easy memory expansion. I'm thinking of...
  16. Best large memory solution for sampler?

    I'm looking to make a sampler with multiple polyphonic samples. I'm hoping to have up to 12 different samples loaded at a time. My initial idea was to use an sd card to store the samples, then load...

    Teensy in a hacksmith video.

    Just watched the newest hacksmith video and saw that they used a teensy 3.6 to control a bionic arm. Not sure if this is the right forum for this - but I thought this was a pretty neat use of a...

    Lots of midi inputs.

    I'm trying to use multiple different midi controllers on one teensy4. What is the best way to connect multiple different midi controllers to one teensy?
    I saw that you can use a usb hub to handle...

    Thanks for all the help, I think I have found a solution which uses much fewer audio rate channels. I'm going to try the satellite idea and have the satellites convert potentiometers and sliders to...

    Could one of the teensy's analog output pins update at 192x the audio sample rate? if so, would it be possible to output a serial signal through the tx pin and then multiplex it when it arrives at...
  21. Most practical way to use lots of audio inputs/outputs.

    I'm designing "control boxes" which act as the io for my teensy project. They have cv inputs and outputs as well as potentiometers and LEDs. The general idea is that I could connect multiple control...

    I was thinking to create an audio object to neaten up my code and audio graph. To implement all the types of synthesis my design needs would take a pretty complex node setup and program. For example,...

    Can i use an envelope output in code?

    I am currently using a dc signal and an envelope to create control signals. However, I need to use these in code and can't find a way to access them.
    I have tried using peak amplitude, but it seems...
  27. Crackling/Clicking noise when note is pressed down (Teensy 4 polyphonic synthesizer).

    whenever a note is pressed down there is a noticeable, but short, crackling noise. This same noise occurs whenever the note is taken off as well.
