Coda write:
it uses $4011 to do cpu
cycle-timed software mixing at around 12khz (different rate, and
different driver for each number of PCM channels from 1 to 4) and
supports some basic instrument macros like mml/famitracker. the cpu
cycle timing actually causes the pitch to vary slightly relative to
the PSG channels across different players, but not
catastrophically. of course whatever the driver does also causes
seeking to break in many players. Downloadand info.
Perhaps the most radical feature of Pulsar is that the synthesis engine runs independently from the sequencer and runs at 180hz – that’s 3 times faster than a “normal” NES audio engine. The advantage of this is that all modulation-based effects have 3 times the resolution so you can get ultra-fast and super-smooth sounds. At the same time it has allowed me to exploit a few quirks of the NES’s audio to provide some unique ways to craft your NES music and sounds.
It was this approach which, to a large extent, dictated the design of the sequencing/UI of Pulsar and why it shares so much in common with LSDJ: LSDJ really makes great use of a simple, fast interface and because I’m updating the audio engine 3 times per frame, speed and simplicity were paramount.
Pulsar borrows heavily from the design, layout and commands of LSDJ. If you’ve used LSDJ you’ll probably be pretty familiar with Pulsar’s UI. There are a few little differences though so watch out for those.
I openly tip my hat to Johan Kotlinksi for his work on LSDJ. It’s safe to say that Pulsar probably wouldn’t exist without it. Or at the very least it would’ve taken me a lot longer to create.
What a Christmas treat!
New in this version:
* GUI improvement and optimization;
* Maemo port (tested on Nokia N900);
* iOS: added screen orientation locking;
* iOS 4 multitasking support;
* iOS: added file sharing (SunVox <-> iTunes);
* added spectrum analyzer;
* new module: OGG Vorbis Player; note: this module is not available
for the PalmOS devices;
* new module: Amplitude Modulator (multiplier);
* added new controller in the “Distortion”: “Noise”;
* added LFO to the “Filter”;
* improved sound quality of the “FM” module;
* improved sound quality of the “Kicker” module;
* added high-quality cubic interpolation to the “Sampler” module;
note: this mode doesn’t work on handheld devices with integer engine;
* added a set of built-in color themes;
* you can specify your own colors using the c_0, c_1, c_2 and c_3
options in the sunvox_config file; example: c_0 #00FF80;

* new keyboard shortcut (pattern editor): CTRL + MINUS – decrease edit step;
* new keyboard shortcut (pattern editor): CTRL + PLUS – increase edit step;
* correct solo/mute handling in the “MultiSynth” module;
* added “Module remapping” function (main menu -> edit -> remap);
* fixed bug with relative note in the “MultiSynth”;
* sunvox_config: added “zoom” option; you can use it for larger
pixels on Linux devices with SDL, or on WinCE devices with RAW video
driver; example of usage: zoom 2;
* added new songs and simple examples;
* many bugs fixed.

The start is abrupt because there’s no play/stop controls etc. just yet. I’ve still only got 2 tracks working so far and we begin with a sort of bass line on the first (top) track. It’s only using square A as you can see by the little red light in the drum patch next to the ‘A’.The first two notes have a pitch sweep applied by setting trigger values in the pattern to affect the LFO width (with a LFO speed of 00, the LFO effectively is a pitch sweep).

ChipdiscoDJ is a twin-deck MOD/XM/S3M player, set up like DJ software and with many of the same features. Needless to say, because modules are much better than MP3s, WAVs and other rendered audio files, you can do very cool stuff by digging into the notes as they’re calculated and played on the fly by the player engine. Adjust speed without adjusting pitch! Change pitch without altering speed! Mute individual instruments or channels! Trigger sub-pattern loops (a la Ableton Live) with pinpoint timing accuracy! Also, because modules are usually very small, you can roll up to a party with ChipdiscoDJ and a bunch of tunes on a floppy disk and kill that shit dead. No floppies? Don’t worry – you can queue up files from other websites by copying the URLs. Aaaawesome.
