OK, here I go. Im nosey !!! "Ally" are you a girl? LOL and "since I was 12". How old are you now? Im just curious because Im 26, and my gorgeous wife is just starting to get into playing piano. I cant teach her (cause I dont have any patience) so shes taking lessons.
Ok, now that I got my nosiness out of me, on to your question. Sorry.
Rackmount or tabletop? Hmmm, thats entirely up to you. Thats just a matter of preference and space to place it. My opinion is this:
Go online to EBAY. Your best bet is an Akai "S" series. Like the S2000,
S2800, or
S3000. You can use your sampler as a drum machine privided that your using an external sequencer with the above mentioned samplers. I use CUVASE VST. Its a computer-base Digital Audio Recording/Midi sequencing. The way that I do it is, Lets just say Midi channels 11-16 I will assign rythym parts as follows:
Midi channel 11 = Closed Hi Hat
Midi channel 12 = Open Hi Hat
Midi channel 13 = Kick Drum
Midi channel 14 = Snare Drum
Midi channel 15 = Cymbals
Midi channel 16 = Toms, and percussion parts: bells, congas, ect.
The above mentioned samplers are fantastic, they are world famous.
The ASR-10 made by Ensoniq is also an awesome sampler. There are many places that sell samples either on floppy disks or cd rom.
Companies like: Kid Nepro, East West, Midimark Productions
Hope that I've helped you. Any questions, just buzz me.
Later,
Mike
