MODEL 250e ARBITRARY FUNCTION GENERATOR is a 16 stage function generator. It is somewhat simpler than the249e, offering one instead of two sequencers, each with 16 stages instead of 24. Each stage stores the values of two control voltages, which are set with an array of 16 potentiometers. Time values are adjusted with a parallel array of smaller potentiometers, and can serve as a third control voltage. Both control voltages and times may be interpolated, quantized, or replaced with externally applied voltages for selected stages. There are also two programmable pulse outputs, as well as a facility for voltage control of stage position. Loop counters are associated with each stage; loops can be nested to any level. Current stage number is indicated with a circular array of orange LED's; edit position is indicated with blue LED's. Editing can be performed while the sequencer is progressing. The 250e's data base can be stored and retrieved with the 225e preset manager. Compared to the 249e, the 250e offers faster access to its variables, and may be preferred in a performance environment. If you're uncertain, try them both, and pick the one that best suits your taste. |
