ARCADE via this auction
"What is it?Sound synthesis through Frequency Modulation (FM) allows to obtain unique sounds that defined a whole musical generation during the 80's and 90's. The model ARCADE uses the YM2151 Yamaha chip that was used in almost all the arcade machines in those years.
What makes it special?
The YM2151 has eight channels with four operators per channel. The operators can interact according to eight different algorithms. Attack-Decay-Sustain-Release (ADSR) envelopes, frequencies and low frequency oscillators (LFOs) can be modified to obtain the whole range of FM sounds.
The YM2151 chip is accompanied by the YM3012 stereo chip that allows converting the digital signal into clear and clean analog sound. Having the separate DAC allows the DAFM synth ARCADE to output a louder and cleaner sound.
The synthesizer is operated through 2 rotary encoders and has a complete menu that is shown in 4 blue OLED displays. Thanks to the beautiful tactile keyboard of 12 notes you can try the different patches as they are created. There is also the possibility of changing the octave and thus test the full sound spectrum of the Yamaha chip. Once created, the presets can be saved in the RAM memory or in an SD card as DMP files that can be opened with VGM trackers like Deflemask.
The stereo sound output is 3.5 mm audio jack, has a MIDI input to connect a keyboard, sequencer or any MIDI instrument and can be powered with a USB Type B cable (5V)."
GENESIS
via this auction
"What is it?Sound synthesis through Frequency Modulation (FM) allows to obtain unique sounds that defined a whole musical generation during the 80's and 90's The model GENESIS uses the YM2612 (or YM3438) Yamaha chip that was used in the SEGA Genesis / Megadrive home console.
New Version 1.77 includes presets from iconic Genesis/Megadrive videogames like Sonic the Hedgehog 1, 2 and 3; Streets of Rage 1 and 2; Toe Jam & Earl, Panic on Funkotron; Ecco the Dolphin; Time Trax; Thunderforce IV and Chakan - The Forever Man in the bank 0. Bank 1 is used for loading up to 128 presets from the SD Card. Check the Datasheet below for the details.
What makes it special?
The YM2612 has six channels with four operators per channel. The operators can interact according to eight different algorithms. Attack-Decay-Sustain-Release (ADSR) envelopes, frequencies and low frequency oscillators (LFOs) can be modified to obtain the whole range of FM sounds.
The YM2612 chip has a peculiar form of crossover distortion in the output, which has become known as the "ladder effect" among fans. The YM3438 is a modified CMOS version of the YM2612 with a louder and cleaner sound output and no "ladder effect". The DAFM Synth can be purchased with the YM2612 or the YM3438 chip. Nostalgic retrogamers would choose the noisier YM2612 chip. The YM3438 would be the first choice for the FM-synthesis lovers. In any case, there is an option to dim the OLEDs to reduce noise at the sound output.
