there's no real-time time-stretching in DLS. Workarounds to make samples span across a wide range depend on your instruments really. You can use multisamnples, or timestretch and import as separate samples. Of course you will be increasing the size of your DLS file... A useful one for analog type waveforms (or indeed any kind of abstract sound source) is to use a sample of the shortest possible loop that works - probably just a couple of cycles works best (but be careful about how the pitch is affected by even the slightest error in loop points working at that resolution). This method gives you very small DLS files and you can use the synth features in DLS to shape the sound - filter envelopes etc, that can be consistent in their timing across the whole keyboard. With the right source waveforms you can make everything from pads to basses to effect sounds to ambiences all from a single tiny wav file. -----Original Message----- From: directmusic-bounce@xxxxxxxxxxxxx [mailto:directmusic-bounce@xxxxxxxxxxxxx]On Behalf Of Aaron R Leiby Sent: 06 January 2003 23:28 To: directmusic@xxxxxxxxxxxxx Subject: [directmusic] DSL Instrument Is it possible to create an instrument that does not increase the speed of a sample with the pitch? (like the preserve duration option in Sound Forge). And if not (which I expect is the answer) are there any good tricks besides exporting a bunch of different wavs at different pitches in Sound Forge? Aaron
