I can honestly say that I am really impressed with the Alchemy Mobile software and the folks over at Camel audio who make it.
The initial app is free and impressive on its own.
I liked it so much that I purchased seveal of their refill sound packs at only 5 bucks a piece and they were all great , plus they gave out 25 additional sounds/loops ect for signing up to their page.
This morning when I opened my app and went to load a sound I found out that every pack I had purchased had new upgrades and the synth itself had a free upgrade and now offers four track recording within the app. and the ability to create your own drum loops/ all for the free version mind you.
So I am now in the process of upgradeing to the pro version for only $9.99 and I get •Save song so you can recall your tunes
•Export WAV and MIDI
•8 songs, 75 sounds & 25 loops
•Pitchbend Each Note by sliding your finger left and right
•Virtual MIDI - control Alchemy from other Apps such as Beatmaker
•Save and load individual tracks
•Record remix pad movements
•Mark presets as favourites for easy lookup
•Additional quantize options including triplets
•Additional keyboard scales
•Auto Sync to External MIDI tempo
•Poly control - set the number of notes to play at once
•Latency Control - balance polyphony vs. latency
•Remote Control of Alchemy or Alchemy Player on your desktop computer
•Load Alchemy Desktop presets
•Download Mobile Version of any desktop sound libraries you own for free
•Polyphonic pitchbend and aftertouch sent to desktop Alchemy
I am also going to order the other two soundpacks i wanted while I am at it just because I am so happy with a company who supports their products so well. KUDOS to everyone and you can check out the software here for the ipad/
