Multi-stage musical instrument amplifier having distortion modes
AbstractA first amplifier stage receives electrical signals generated by a musical instrument and provides an output signal. A second amplifier stage is driven by the output signal from the first amplifier stage as switch selectively connects an attenuator to the first amplifier stage to attenuate the output signal thereof and selectively connects a gain modifying circuit to the first stage. In a first mode, the attenuator is connected to the first amplifier stage and the gain modifying circuit is disconnected from the first amplifier stage. As a result, an output signal from the first amplifier stage has a level which drives the second amplifier stage to provide a substantially linear output signal therefrom. In a second mode, the attenuator is disconnected from the first amplifier stage and the gain modifying circuit is connected to the first amplifier stage. As a result, an output signal from the first amplifier stage has a level which will overdrive the second amplifier stage to provide a non-linear saturated signal therefrom having a first desired amount of increased harmonic saturation.ClaimsWhat is claimed is:
Device for and method of detecting and supplying chord and solo sounding instructions in an electronic musical instrument
AbstractAccording to the invention, a new sounding operation changes a solo being played, and various ways of sounding musical tones are permitted by a selection of whether or not a chord being played is to be changed. In response to an instruction for sounding a musical tone, chord tone data is provided together with tone data indicating a single key number, to thereby determine whether or not the chord is to be detected, and whether or not chord tone data is be output. Accordingly, ways of sounding musical tones, such as changing a chord being played together with a solo being played, or not changing a chord being played but changing only the solo being played.ClaimsI claim:
