sound environments : part 2 : step by step

>Andrew, >How about some Step by step instructions for us dummies? >Thanks. no problem. Here's another tutorial :) [1.] Make a patch using a looped table. [ this is done using the table editing described previously ] I listed the keys to add waveforms (for the first entry in the table section) --- in the same entry as the waveform you can add [Loop] (followed by the amount of times it loops -- be sure to press 0 then then the loop amount -- is up to 9 i think?) and [End] ends the tables and continues the patch sound. This is done with keys "8" and "9" respectively. Other keys for your reference --: "1" Adds "S" to the middle entry [ 00 Tri S- --- ] "2" Adds "R" to the middle entry [ 00 Tri SR --- ] For the last entry, you use "1" "2" and "3" to add (transposition?) respectively : [ 00 Tri SR F00 ] [ 00 Tri SR -00 ] [ 00 Tri SR +00 ] Moving along to the end you get an arrow, where you enter a number with the numberic keypad which is the value. onwards! :) [2.] Add [Loop] at the end of your sequence with a 00 value (loops infinitely). [3.] When you key down, you'll get a constant looping table sequence. [4.] Now! take your fingers away from the keyboard. Now boost the gain of your mixer (you'll need gain/level control to boost the output level) until you can hear the table playing it's ghost noise (sounds like electronic interference). [5.] You can play with the real time controllers on the SID, or from your external controller. Pitch bends and filter sweeps will effect the table (which is still playing, cause the envelope never fully closes). The sound is very distant and faint. [6.] Put this through a nice long delay/echo (analogue style delays are best, with the filtered echo) .. then play! Don't touch the keyboard though, you'll blow your speakers (and ears!) ;) [7.] You're now well and truly inside the MOS6851 ! (try headphones with the resulting recording or live). [8.] try it with all your patches, each one creates its own unique ambient soundscape --- some like the evolving clouds Erik Weik has spoken to me of... enjoy.. Andrew
