I'm sorry but I'm not aware of a specific product named "Akai AP-Q70 C." Please double-check the name and let me know if it's a misprint or if I'm missing something. If you're referring to the Akai Professional APC40 MkII, it's a MIDI controller designed for Ableton Live, which comes in different colors including black (APC40 MkII) and white (APC40 MkII - White Edition). However, there's no letter "C" as part of the product name. It's possible that you might have mistaken it for the APC 21M, which is also a version of the APC40, but with a built-in motorized fader. You may want to provide more context or clarify the product name so I can better assist you.
