C64Music!

New revolutionary C64 music routine unveiled

A team of supertalented coders have managed to break the limits of C64 sound once again.

The Human Coding Machine from Germany and SounDemoN from Finland, have managed to create a music routine that allows you to have:

- 4 channels of 8-bit samplerate, digi playback
- 2 channels of SID synth sound
- You can filter both SID channels AND SAMPLES!
- And you have enough rastertime to not being forced to turn off the screen, and can actually do something with it ;)

This technique has been presented in the X'2008 demoparty, the bi-annual classic of the C64 scene where usually all barriers are broken and this one has been, fortunately, no exception!

The routine in question was demo'ed in the production VICIOUS SID (picture), which also included other crazy audio routines you can check out by following the attached link.

Beta testing of this software will start soon, a few artists have started to experiment with pre-beta versions of the tools, like Fanta, who made an amazing X'2008 SID music entry with his tune Fanta in Space, which you can check out by clicking here.

(this is the output straight from a Commodore 64, nothing added!)

How to code your own music player in Assembler!

From the UK comes a nice 30min video tutorial for beginners on how to write a simple raster IRQ setup and run routine in assembly language for the Commodore 64, using Action Replay for a monitor/assembler.

This example is on how to write a simple music player with an IRQ. (Part 1/4)

Goto80 unveils his secret tool!

Yeah.. Goto80 has been telling us since a few months about a secret tool called DefMON, made by one of his pals, so in theory no mortal will ever play with it..only Goto80, so, now we get to see the first video of the tool in action and my first impression is that DefMON makes the SID synth spit out some data-fire !!! yeshhhh !

enjoy the fresh breeze.

MUSICVIDEO_Il Creatore "Dei Pupazzi"

Following the paths of Florian Schneider, Telex and Hubbard comes Il Creatore, this musician based in Rome published three albums full of Vocoder, Sidstation and C64 vibes. Here goes the video "Dei pupazzi" from "Animali da riproduzione".

HyperSID synthesizer

I'm not really sure now, but I think among all the SID based synths I've checked out I've never seen this one so here it goes.

The HyperSID, a Subtractive Hardware Synthesizer based on the C64 SID Chip, you control it via MIDI and also with a custom built VSTi that controls all the parameters in the synth. You will find documentation and downloads in the official website.

Features:

- 3 OSC per key (Monophonic)
- 1 OSC per key (3 Voice polyphonic)
- 4 Waveforms per OSC Tri , Saw ,Noise, Pulse (combinatorial)
- OSC transpose range +36 to -36 Semitone
- OSC cent range -50 to +50 Cent
- OSC ring modulation
- 3 Amp Envelope ADSR
- Multimode analog filter 12dB/Octave HP , LP , BP and (combinatorial)
- 1 LFO Part with sync , retrig and invert capability
- 1 Step LFO Part with sync , retrig and invert capability
- 2 General purpose envelope generator with invert capability
- Individual routing for each modulation source
- 88 Parameter for controlling overall synthesizer (automation recordable)
- Flexible preset manager with save and load function
- Built in 64 categorized Factory preset .
- Clean sound without any Self oscillating in most of the Presets
- Automatic real time synchronization between software and hardware
- Independent MIDI out path from host
- Very low CPU usage

Commodore 64 Cynthcart: Syncing a filter sequencer to LSDJ

Using a similar setup to the previous post, it is quite simple to build / add a sequencer section for standalone operation. Furthermore, if this sequencer is clocked using an external source (such as... LSDJ!) then it can be quickly synchronised to other sources of music.

The program Cynthcart is running on the Commodore 64. The filter is usually controlled by a paddle control in real time. However, it is easy also to sequence the filter frequency using some cheap IC's.

In this case, the speed of the sequencer is controlled by the master clock sync output from LSDJ running on the Gameboy.

Auto filter interface for C64 using Arduino

I have been recently enjoying the exquisite stuff that Sebastian Tomczak is posting through his little-scale blog, lots of cool chip-data-hacking action for your brain.

One of the latest is this great arduino based idea, a software / hardware combo that allows for control of the analog filter inside a Commodore 64 that is running Cynthcart from a host computer (eg, Macbook, PC).

Software
• 16-step filter sequencer
• Set the speed of the filter sequence (with intervals between values reaching 2ms)
• Set the length of the sequence from 1 to 16 beats
• Offset value allows for shifting the filter values up or down on a larger scale
• MIDI mode allows sending data directly to control the filter (this mode disables the sequencer)

The hardware is very simple, and is based around an Arduino board that is using a bit-banging SPI technique to write data to a 100KΩ digital pot.
