Whereas David Whittaker accomplished some great 48k and 128k pieces of music, the next time you hear some realistic five channel music from your Spectrum or Spectrum emulator, just bear in mind one name: "Tim Follin". Tim was the musical wizard who accomplished some great sounding five channel sonics from the Sinclair 48k Spectrum, with some of the finest layered dinamic's ever to grace the Sinclair Spectrum's 48k's internal speaker. Tim was always one step ahead: he fine tuned his techniques to absolute perfection. His multi channel compisitions began with the likes of the musical masterpieces of such computer games as the Agent X I and II theme and also Chronos on the Sinclair Spectrum, which were all released on the Mastronic label. However, it was Tim's music in "Agent X II" in which he truly perefected his multi channel sound routines with the best sounding sonics to ever grace the Sinclair 48k Spectrum. Whatsmore who could ever think you could get a drum snare out of Sinclair's 48k Spectrum?

I provide Tim's machine code route as printed in a "Your Sinclair magazine in the year 1987, as a fitting tribute. Hopefully he does not mind. It was published under the heading of "Star Tip 2" which was printed in the "program pitstop" section of the magazine".

His piece of code demonstrates some very clever trickery by squeezing four channel music out of the Sinclair 48k Spectrum. The machine code for this routine starts at address 40000, and is 1340 bytes long. I also provide the routine in TAP and TZX formats for you to load into your Spectrum emulator if you wish to save yourself some typing (download it by clicking the links below).

His routine provided here is how it was originally printed in Your Sinclair (raw machine code printed as a huge hex dump). For entering this hex dump you will of course, require 'Your Sinclair' Magazine's 'Hex Loader' which was a BASIC program for entering their huge machine code hex dumps which appeared in the magazine each month which readers would often send into the magazine. The YS hexloader program I do not have, but you can find it in the 'Program Pitstop' section of the magazine. Type in the hex loader program and run it. Next, you will be asked to enter a start address, so type in 40000 [ENTER]. Now enter the 16 lines of hex for this line then press [ENTER]. You will be asked for the checksum for this line (it appears in the listing below after the equals sign). For 40008 and all subsequent lines thereafter just type in the 16 lines of hex for each line and the checksum (the number after the equals sign). When you have finished typing in this huge hex dump, quit the YS hexloader program, by entering STOP [return]. Then make sure you have a blank casette handy and save all the machine code with SAVE "TUNECODE" CODE 40000,1340.

If you do not have 'Your Sinclair' magazine's hexloader program to type in the machine code below, then do not worry! I have also provided a machine code disassembly suitable for an assembler such as Devpac with numerical values printed in hex or decimal (depending upon what your assembler prefers).

I include his composition also as an MP3 for those that do not have a Spectrum or Spectrum emulator which you can download by clicking this link (0.5 megabytes) which you can load into any suitable MP3 player such as Windows Media player.
