Insights into the strophonion's software configuration (status June 2018) based on the audio processing software Max 7
Sukandar Kartadinata who programmed and developed the configuration in Max 7 explains its architecture in 3 minutes and 55 seconds
Max 7 is an audio software application distributed by Cycling '74, a California-based company that, according their website, 'connects objects with virtual patch cords to create interactive sounds, graphics, and custom effects.'
Note that the functionality chart is an indispensable mnemonic device to quickly re-learn the instrument's functionality once the musician takes a break from practicing lasting longer than two weeks. This is due to the intricate software architecture that provides multiple layers of functionality and playability. Both has been necessary to be implemented in order to endow the performer with great flexibility in many regards. For the strophonion serves as sampler capable of live recording sounds and as synthesizer which modulates and manipulates the just-recorded and/or pre-recorded sounds. The instrument provides 100 pre-recorded samples based on ten sample banks each containing ten samples. The strophonion also functions as keyboard whose range is, theoretically speaking, unlimited. Practically, however, due to the nature of the hearing capabilities of the human ear, low and high ends do of course exist. The range in which it usually makes sense to play encompasses twice the one of the piano. The question about when the human ear starts to be no longer able to perceive the transposed sound as played varies largely depending on the actual sound properties of the selected sample and the amplification system used through which the sounds are disseminated.
