ROUGOL logo Welcome to
RISC OS User Group Of London



ROUGOL is a not-for-profit organisation consisting of RISC OS users in London and the south-east. Our aim is to bring those users together. There is no membership fee and entry to all meetings is free. To find out more, email us.


Meetings are held on the third Monday of every month. Most meetings feature a guest speaker, demonstrating the latest hardware or software, giving tutorials of software both new and old, or simply to kick off discussions on the current hot topic. Entrance is free, so why not come along and say hello?


The next RISC OS London Show is on Saturday 29th October 2016.

Next meeting - Monday 21st November 2016 
Sound Synthesis and 3D Graphics - Anthony Bartram, Amcog

Antony Bartram is currently developing a sound synthesiser for RISC OS, based on Wavebox for Windows.

Although the code is based on the Wavebox DSP, the sound engine is different. Inspiration is drawn from the BBC Micro, Amiga and analogue synthesisers to try and create something distinct and geared towards chip tunes and sound effects.

Each of the 8 sound channels has the following signal path:

As if that wasn't enough, Anthony will also be talking about the 3D modelling used in his space game, Xeroid, and explaining how the 3D projection works. All done in plain BBC BASIC.

Since Anthony released his first game Overlord 18 months ago, he has gone on to release Xeroid, Legends of Magic, and most recently Mop Tops. Each has featured full soundtracks with new tunes produced by Anthony. There should be plenty of time to play with these, and maybe buy a copy if you missed them at the London Show!
