The SE-50 is a multi effects unit. It was released 1990 and was in production until the SE-70 was released 1993. The unit is equippped with a 16 bit DA/AD converter and uses a sampling frequency of 32kHz or 48kHz depending upon the chosen effect. The SE-50 has both stereo in and out, is fully MIDI compatible and its 100 user presets can be stored externally using the MIDI interface.
The SE-50 has 28 built-in algorithms. An algorithm is a predefined combination of effects. Several of the 28 algorithms are single effect algorithms so thought it may sound like the SE-50 can combine effects in many ways, this isn’t absolutely true. Guitar players may be interested to know that the only algorithm capable of producing distortion is Guitar Multi and the only settings for the overdrive/distortion is level/drive and turbo on/off. The unit is very much focused on reverb where 9 of the 28 algorithms are reverb only algorithms.
There are 128 presets. Preset 101-128 cannot be overwritten as they demonstrate each of the 28 algorithms. Preset 1-100 are user programmable and by copying one of the 28 fixed presets into one of these locations a start position with the chosen algorithm is easily achieved.
The 28 algorithms:
|1||Hall 1||Natural hall reverberation|
|2||Hall 2||Hall reverberation with mid boost|
|4||Plate||Simulation of a metal plate vibrating to produce reverb|
|5||Ambience||Ambience microphone reverb|
|6||Gate Reverb||The reverb is muted partway through|
|7||Stereo Reverb||Two channel reverb with common settings for both channels|
|8||Multi Delay||5 delays in a row|
|9||Multi Tap Delay||5 delays in a row with different settings than Multi Delay|
|10||Stereo Delay||Delay with independent settings for each channel|
|11||Space Chorus||A slightly pitch shifted signal is added to the original signal|
|12||Multi Pitch Shifter||4 parallel pitch shifters adjustable to +/- 2 octaves|
|13||Stereo Pitch Shifter||Independant pitch shifting on each channel adjustable to +/- 1 octave|
|14||Stereo Flanger||A flanger and gate effect connected in series|
|15||Stereo Phaser||A phase shifted signal is added to the original signal|
|16||Vocoder||Requires a microphone to R input and keyboard to L input. Has a chorus and noise supressor connected in series from the vocoder’s output.|
|17||Rotary||Simulates a rotary Speaker. Has a noise supressor in series with the rotary’s output|
|18||Keyboard Multi 1||A stereo series consisting of: Equalizer – Delay – Chorus – Reverb|
|19||Keyboard Multi 2||A stereo series made up of: Phaser – Equalizer – Chorus – Reverb|
|20||Rhodes||Simulates Fender Rhodes electric piano sound using a stereo series of: Equalizer – Phaser – Noise Suppressor – Chorus – Panning – Reverb|
|21||Guitar Multi||A stereo series consisting of: Compressor – Overdrive/Distortion – Equalizer – Noise Suppressor – Delay – Chorus – Reverb – Line Driver|
|22||Vocal Multi||A stereo series made up of: Limiter – Enhancer – Noise Suppressor – Delay – Chorus – Reverb|
|23||Stereo Enhancer||A stereo series made up of: Limiter – Enhancer – Noise Suppressor – Delay – Chorus – Reverb|
|24||2 Channel Mixer||This algorithm consists of Equalizer, Noise Suppressor, Delay, Chorus and Reverb. The 2 first effects are applied separately to each channels while the latter 3 can be panned right and left|
|25||Reverb1 + Reverb2||Separete reverb for each stereo channel|
|26||Gate Reverb + Reverb||Gate Reverb on left channel, conventional reverb on right|
|27||Chorus + Reverb||Chorus on left channel, reverb on right|
|28||Delay + reverb||Delay on left channel, reverb on right|
