VirSyn is a company that's well-known to Mac and PC-based music makers, and now it's stepping into the iPhone/iPod touch domain with the launch of the iSyn Virtual Music Studio.
This has been produced in collaboration with audioMIDI.com, and features two fully programmable virtual analogue monophonic synths and a fully editable sample-based drum machine that offers eight different kits (808- and 909-style soundbanks are among those included).
Notes and beats are played via the onscreen keyboard and eight pads, and there's also a grid sequencer that supports two synth tracks and one for drums. Parameters can be adjusted via an X/Y touchscreen or by tilting the iPhone/iPod touch to make use of its motion sensing capabilities.
iSyn can hold up to 32 song projects, each of which can contain 32 independent patterns, and there are delay, chorus, flanger and phaser effects. It's available now from the Apple App Store and costs $4.99/£2.99.
