Stream FFT and iFFT
Author: Unknown. Martin?

Oh boy, yes, this was an early attempt of mine , now totally obsolete since we have stream FFT up to 32k or more. Anyway, thank you for taking the effort of doing this, Spogg.

Thought so! I've updated the post.
I realise I've been spelling your name wrong too

It may well be old and superceded but it still impresses me

Continuous blend knob

Now here's an interesting knob! It rotates continuously and the output is a varying blend of values determined by its configuration.
The author has provided detailed instructions and given 3 examples to demonstrate some possibilities, including an LFO which morphs smoothly between 4 waveforms.

BPM generator and analyser

This schematic allows you to generate an accurate BPM and also analyse an audio signal to extract and display its BPM.
The author has provided a basic drum sample to test and demonstrate.

Spogged: Added a knob to set BPM and re-arranged the schematic layout a little. Sometimes these old Synthmaker schematics seem to have messed up layouts with modules superimposed.
Also note that I haven't tested with real-world drum loops, so maybe someone can do that and report back...

Collection of radio buttons

Here's a collection of "radio buttons". The term arises from old-school radios where only one wavelength or program button could be pressed in at any one time. Pressing a different button releases the previous one.

Spogged: Nothing

Authors: Various. Please see the filename where the author has used initials or name.

Lowpass, highpass and bandpass filters

A collection of filter types to compare response curves. You can choose the filter type and number of poles and see the resulting graph. The Q or resonance for each is set internally for some but could easily be bought out to a knob or knobs I guess.

EDIT: added highpass and bandpass to lowpass and zipped together

32 sliders from 8

Fascinating! This is a nice looking panel with 4 pages each showing 8 sliders, so there appears to be 32 unique sliders. The twist is that there are only 8 sliders used. Their values are stored in an array (which can be saved) so when you display the page you want, the positions are recalled for that page. This is not view switching but a lot of cleverness!

Spogged: I wasn't sure what you could do with the created array so I added a simple get-at schematic inside the module. Using 32 of these you could control 32 levels for instance. I bet there's a better way than this but I just wanted to test the system. I'm not sure how this would integrate with a preset manager but I guess the idea is to store and recall the array rather than each virtual slider's value.

Hey Spogg... just wanted to pop in and say thanks for all this work you've put in!

Time-based unique filename creator

A nice simple idea to create a unique filename ready for saving. The current time forms part of the filename you specify.

Spogged: Originally this was just the module so I added a trigger button and some string prims for demonstration. For newbies this also nicely illustrates the importance of connection order and the summing nature of inputs.

Half and full wave rectifier

Here is ready-made DSP code to convert a waveform into half and full wave rectified versions. This can extend the range of any oscillator or signal with a +/- range.

Spogged: Added an input level knob and input scope for demo. Note that using this for audio will provide a positive-going waveform only, so in practice I would recommend following this with a dc blocker, especially when using delays.
