QuickLZ compression for ByteStrings This package provides a high level binding to the QuickLZ compression library for ByteStrings, under the GPLv2 license. QuickLZ is fast and compresses very well. Check out the home page: http://quicklz.com This package includes the QuickLZ 1.5.0 source code, at compression level 1 and streaming mode disabled. The versioning scheme for this package is unusual. QuickLZ tries to be as fast as possible, and will break backwards compatibility to achieve it in newer versions. This versioning scheme reflects the QuickLZ versioning scheme: the first three digits of version w.x.y.z are the quicklz version, with the z component (and any further needed ones) being updates to this package, not quicklz itself.

Divide without division Generate routines for integer division, employing arithmetic and bitwise operations only, which are 2.5x-3.5x faster than quot. Divisors must be known in compile-time and be positive.

Binding for the rdtsc machine instruction This module provides the function rdtsc for accessing the rdtsc machine register on modern IA-32 processors. This is a 64-bit counter which counts the number of processor cycles since the machine has been powered up. Using this instruction, you can make very precise time measurements which are independent of the actual CPU frequency. But note that you can get strange results sometimes on a superscalar processor. Also note that the Haskell foreign function interface imposes some additional overheads. On my machine, it takes about 950 cycles to call this function twice and to compute the difference, whereas in C the overhead is only about 88 cycles.

Process MIDI events via reactive-banana MIDI is the Musical Instrument Digital Interface, ALSA is the Advanced Linux Sound Architecture. This package allows to manipulate a sequence of MIDI events via ALSA. It is intended to be plugged as a playing assistant between a MIDI input device (e.g. a keyboard or a controller bank) and a MIDI controlled synthesizer (e.g. a software synthesizer or an external synthesizer). For software synthesizers see the Haskell packages synthesizer-alsa, synthesizer-llvm, supercollider-midi, hsc3, YampaSynth or the C packages fluidsynth and Timidity. Applications include: Remapping of channels, controller, instruments, keys, Keyboard splitting, Conversion from notes to controllers, Latch mode, Convert parallel chords to serial patterns, Automated change of MIDI controllers, Delay and echo. It is intended that you write programs for MIDI stream manipulation. It is not intended to provide an executable program with all the functionality available in a custom programming interface. It is most fun to play with the stream editors in GHCi. However we provide an example module that demonstrates various effects.
