Macchi C.202
The Macchi C.202 Folgore (Italian "thunderbolt") was a World War II fighter aircraft built by Macchi Aeronautica and operated mainly by the Regia Aeronautica (RA; Royal (Italian) Air Force). Macchi aircraft designed by Mario Castoldi received the "C" letter in their model designation, hence the Folgore is referred to as the C.202 or MC.202. The C.202 was a development of the earlier C.200 Saetta, with an Italian-built version of the Daimler-Benz DB 601Aa engine and a redesigned, more streamlined fuselage. Considered to be one of the best wartime fighters to serve in large numbers with the Regia Aeronautica, the Folgore operated on all fronts in which Italy was involved.
The Folgore went into service with the Regia Aeronautica in July 1941 and immediately proved to be an effective and deadly dogfighter. The Australian ace Clive Caldwell, who fought a wide variety of German, Italian and Japanese fighters during 1941–45, later stated that the C.202 was "one of the best and most undervalued of fighters". The C.202 also had its defects: like its predecessor, the Macchi C.200, it could enter a dangerous spin. It was insufficiently armed, with just two machine guns that easily jammed. The radios were unreliable, forcing the pilots to communicate by waggling wings. The oxygen system was inefficient, causing 50 to 60 per cent of the pilots to break off missions, sometimes even causing fatal accidents.
Roland MC-202
The Roland MC-202 (MicroComposer) is a monophonic analog synthesizer/sequencer released by Roland in 1983. It is similar to the TB-303 and SH-101 synthesizers, featuring one voltage-controlled oscillator with simultaneous saw and square/pulse-width waveforms. The unit is portable and can be operated from batteries or an external power supply.
Synthesizer
The internal synthesizer features one voltage-controlled oscillator with simultaneous saw, square/pulse-width and sub-octave square waveforms. Additionally there is a 24dB Low Pass filter, an LFO and a single ADSR envelope generator.
In terms of circuitry, it is nearly identical to the earlier SH-101 synthesizers but lacks the noise generator, choice of LFO shapes and modualtion/pitch bend controls. However, unlike the SH-101, it does include a delay on the LFO. The two units also share a design aesthetic in terms of the control layout, casing, lettering, knobs and slider caps.
Sequencer
The MC-202 includes a sequencer that can play back two separate sequences simultaneously. Two sets of CV/Gate connectors on the rear of the unit allow for routing the sequences to external synthesizers. One of the two sequences is used to control the internal synthesiser. The sequencer is programmed much like Roland's early digital MC-4 and MC-8 Microcomposer sequencers, whereby notes are entered with pitch, length and gate length. Additionally, each note in the sequence can have an accent and slide, which is similar to the TB-303 and the SH-101 and allows for so called acid sequences.
