BL R-series engine fitted to the Maestro with the carburettor facing the front of the car, which also led to a reputation for carburettor icing in cold weather. The endemic problem of crankshaft failure was later attributed to flexing of the crankcase – because the E series relied upon the heavy sump/transmission unit to give additional strength to the cylinder block casting, this caused problems when a plain sump was bolted in its place. The R series was superseded in 1984 by the S series. BL R-series engine The R series is a line of petrol engines introduced by British Leyland in 1983
Spire (synthesizer) analog synthesizers. There are seven modes available for each oscillator: "Classic", "Noise", "FM", "HardFM", "SawPWM" , "AMSync", and "Vowel". The sounds from the four oscillators can then be routed to the modulation units, which include four envelopes, four Low Frequency Oscillators, two step sequencers, and routing matrix. There is also an effects section, which contains five effects: delay, phaser, chorus, reverb, and waveshaping. Spire (synthesizer) Spire was the first software synthesizer developed by Reveal Sound. The synthesizer utilizes multipurpose oscillators, filters, and effects units within a digital graphic interface. Spire combines elements from both Analog and software synthesizers. The synthesizer
