This operation will take from 6 to 12 minutes depending on the sysex file source (e. g. With Page 7 selected, press Yes Erase existing code by pressing Enter Update M20 software Initiate send at transmitting device (if using an M20, see section 12. 6) Wait for load operation to end (approximately 6 minutes from the Alesis sourced MIDI file, 12 minutes from another M20). The machine automatically restarts. 12-2 ALESIS M20 REFERENCE MANUAL 1. 06 Chapter 12, MIDI Functions Before loading new software into your M20, always save a "backup" of the existing software in the M20 to your computer sequencer or data storage device. This will safeguard against any mishaps that could occur during the software loading process (i. e. corrupted MIDI file, equipment failure, etc. ). WARNING: If the M20 loads an incomplete update or incorrect data, the main display will show an error message. If a software load attempt fails, it is necessary to properly load the software before using the M20. The M20 will be nonfunctional until the operating system is successfully loaded. You will need to power-cycle the M20 (turn the unit off then on again) after an incomplete load. When the M20 restarts, the main display will prompt you to erase the software again. For more on M20 software, see Tutorial 6 in Chapter 15. ALESIS M20 REFERENCE MANUAL 1. 06 12-3 MIDI Functions, Chapter 12 12-4 ALESIS M20 REFERENCE MANUAL 1. 06 CHAPTER 13 UTILITY MENU There are 22 pages of Utility functions. Shortcut: To jump directly to a particular page, hold Utility down and enter the page number form the keypad, using leading zeroes to access pages 01-09. 13. 1 DIGITAL OUT (PAGE 1) Selects the digital output format and resolution for tapes formatted in 20-bit mode (there is no choice of digital output with 16-bit tapes). Procedure: Use the Up/Down buttons (or keypad buttons 0-4) to choose among the following: 20-bit (default). All 20 bits of audio are available at the optical and I/O card outputs. The digital audio optical output from a 20-bit tape or digital input source is dithered down (using the 4 least-significant bits of the 20-bit signal) to a 16-bit output. This simply truncates the 4 least-significant bits from a 20-bit tape or digital input source. The digital audio input from an optical or I/O card source goes directly to the optical or I/O card output. The source word length is unchanged. 13. 2 ONLINE SOURCE (PAGE 2) Sets the control source when Online mode (section 13. 2a) is enabled. Procedure: Use the Up/Down buttons (or keypad buttons 0-3) to choose among the following: ADAT (default). [. . . ] Note the following when using Aux Track routing: · · Aux routing play back through the "AUX" selected channels is defeated when Digital Scan mode is enabled. Cue and review scanning will always output audio at ­6 dB regardless of the DigScan status and the attenuation setting. I/O CARD AS THE DIGITAL SOURCE · The "D" indicators in the Meter Display are now always lit solid when the Digital Source is I/O Card and the Clock Source is from a source other than I/O Card (even when the selected clock source is not present). When the Digital Source is set for I/O Card, there are some limitations on the routing. Basically, the AES/EBU and analog input share the routing, i. e. , they are one in the same. [. . . ]
