Here's a little trick - you can use any lo-fi sampler to try this, such as a Casio SK-1/5 or 8 etc, or a yamaha VSS sampler. I used my Casio SK-8. I also tried it on my Casio FZ-1, but its better on a low quality sampler.
Basically, you take a recorded sound source, for example, a 45 rpm 7" vinyl single record, of say, a drum beat or something. Hook up a record player up to the SK sampler line input. Play the record at its normal 45rpm speed.
Record this record into the sampler on a sampler memory. Play it back. It should sound like the record, only poorer quality, obviously, as the SK is a lo-fi sampler.
Repeat the recording on another sample voice memory so you can compare it to the first sample (only on the SK5 and 8 will you be able to keep the first one as well, though. On the SK-1 which has only 1 memory, record your SK on a computer and then overwrite the sample with the next one, record it to computer, then compare the 2). Only this time, slow the record down to 33rpm. Record the sample. Play it back. It should sound like the slowed down record. Now play the sample back 4 or 5 notes up on the keyboard, so that the sample is tuned up to the same as the record's pitch and tempo as it should be played at 45rpm.
Compare the first sample and the second "tuned up" sample. Tell me what you notice.
If you don't have a record player, you can use your computer in place of it, and use a wav file of a good quality drum beat. In this case, use a soft sample player or program to slow the playback of the wav file down - you can be even more extreme than the record player in this case - tune it down a whole OCTAVE.
- Make sure you don't slow it down using a "time stretch/pitch shift" type of software effect, where the pitch can be dropped but the beat stays at the same tempo - in this case, we want it to work just like the slowed record - where the pitch drops an octave AND the tempo slows down by half.
Now, when you play it back on the sampler, play it back a whole octave up to play it at the same pitch and tempo as the original wav file.
Tell me what you think!!
