IBufWr, an interpolating buffer writer

v.1 by Pierre Alexandre Tremblay (2018)

Description

This is a SuperCollider (https://supercollider.github.io/) porting of the bespoke Max (https://cycling74.com/products/max) object ipoke~ v4.1 (http://www.no-tv.org/MaxMSP/), which allows to write to the server buffers without leaving unfilled indices when writing faster than realtime.

Why was this utility needed

It was impossible to emulate the musical behaviour of bespoke resampling digital delay pedals in Max and SuperCollider. Now it is.

How to Install from binaries (SC 3.9 on Mac required)

Download the package and read the text file.

How to build from the source code

These instructions are modified from the amazingly streamlined UGen writing tutorial by snappizz (https://github.com/supercollider/example-plugins)

1. Download the SuperCollider source
2. Create build directory
3. cd to the folder where IBufWr is
4. create a build directory
5. cd into it
6. Set the compiler options and build
7. set the make parameters by typing cmake -DSC_PATH=PATH_TO_SUPERCOLLIDER_SOURCE -DCMAKE_BUILD_TYPE=Release .. 5. for a MacOS fat binary add -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" - or for a personal copy the option -DCMAKE_CXX_FLAGS=-march=native will optimise as fast as the machine will go, at the cost of compatibility with other hardware.
8. type make, it should compile.
9. once it is done, install the Ugen and its Declaration by moving them in the release-packaging/IBufWr/classes and 'release-packaging/IBufWr/plugins' respectively, then move the whole IBufWr folder in your Extensions folder.
10. for MacOS this is where code signature and notarization has to happen...

Enjoy! Comments, suggestions and bug reports are welcome.
