[Zero IDM content question approaching - sorry Alan...] Whilst we're on the subject of locks, anyone know how they made? Because, thinking about it, the groove needs to be the exact length of the bar. Therefore depending on the length of the bar, the groove needs to be in an exact position, a fixed distance away from the centre. How does this get worked out? || [CiM] || u9323899@sys.uea.ac.uk || http://www.sys.uea.ac.uk/~u9323899/

45 rpm is 45 rpm be it in the center or on the edge of the record. Check it out. --->13013 On Tue, 26 Sep 1995, CiM wrote:

...or anything else, for that matter. The masters of this technique, IMHO, are Canada's own Legion Of Green Men. They've been doing them for years, starting with their noise-ambient work under the name Electro Static Cat (aka Emperical Sleeping Consort), and moving towards the multitude of locked grooves that they put on all their vinyl releases as LOGM, Alkahest, etc. Greg

Records rotate at a constant speed, so one revolution of the record takes a fixed period of time no matter where the groove is located physically on the platter. All you have to do is match the tempo (if any) to the length of a single rotation to get a BPM that's a direct multiple of the turntable speed (like 100 or 133 1/3 bpm at 33 1/3; 90 or 135 bpm at 45). -- ::: Lazlo (lazlo@swcp.com; http://www.swcp.com/lazlo)

Which means that the outer grooves are longer, and the wiggles in the vinyl are more spread out, compared with the inner grooves. That's why long (> 40minute) LP's tend to sound shitty on the inner tracks: more wiggles are packed into a shorter linear groove. -- kent.williams@cadsi.com [Kent Williams/CADSI/2651 Crosspark Rd/Coralville IA 52241/(319)626-6700] "It is a good world, generally (and especially when totally ignore detail)." --Darwin Grosse, who did NOT invent Eckankar.
