“store” any information within the software itself. CONCEPT TO KNOW #3: Each time a Theory ALC is powered-up, the DSP chip is initially “empty” - it does not remember any of the filter settings or programs. At power-up, an on-board micro processor loads the DSP parameter settings from on-board ALC memory. - Page 19 CONCEPT TO KNOW #5: In order for a Theory ALC to “remember” DSP settings when powered off and then powered up again, your settings must be stored into the on-board flash memory so that they can be loaded by the microprocessor during the power-up “initialization”...
