The infamous and all enlightening BenO statement about Multitrack recording.

Unfortunately, this is not possible with the current DL1608 hardware.
There is only one way that's possible and that Mackie implemented V1.1 USB, That's a 1995 issue spec and this mixer was started in 2010 (iOS 4 era). The USB V3.0 was issued in 2008. Talk about state of the art. The V1.1 could only handle 12Mbits on paper thus 17Mbits as required by 16 tracks at 44.1K without overhead would be impossible. There is just one problem with that theory, IT"S NOT HARDWARE!!! This is a digital mixer and after the A/D converter it's software moving numbers around until you send it back to analog via the D/A converter. Sending the data to the iPad won't even be noticed by the Tuna (Blackfin) on a USB 2.0 480Mbits on paper, 250Mbits real world transmission rate. The USB implementation is also not restricted to V1.1. The code is available from Analog Devices for V2.0 etc.. Next, the iOS v4 had usable multitasking implemented which would make multitrack a lot easier. Apple may not have provided more than 2 channel audio recording API's but that's why 3rd party developers and OEM's exist. They write their own code for this like Audiobus. In closing it's quite interesting to note that 16 channel recording request has not been rejected in the Mackie feature lists. So do you want to believe a marketing droid that can't tell the difference between hardware and software?
