The MIDIpod

Most commercially availabe MIDI expanders for musical instruments are based on sampled signals in order to render a near-authentic sound of the instrument to be represented. Consequently, a lot of RAM is required and in addition considerable CPU power. If in contrast the instrument is represented by a mathematical model, the sound signal that would be produced by the instrument can be simulated. This approach requires nearly no RAM, other then for hosting the computation algorithms, and less CPU. As a result a smaller embedded computing device can be used, e.g. of the size of an Apple iPod. The only constraints on such a device are:

The operation would be simple. Connect a MIDI instrument to the MIDIpod, switch it on, configure the device settings (pitch frequency and other simulation parameters), plug-in your head phones or a power amplifier and play. Such a device could be insteresting for a mobile pianist in concunction with a MIDI keyboard (e.g. Doepfer PK88 as it is small and portable. The MIDIpod could look like that:
