PYRATONE MODULES FOR SALE | |||||||||||||||||||||||||||||||||||||||||
PYRATONE SOUND SYNTHESIS IN YOUR MUSICAL INSTRUMENT: THE MODULE IS SUITABLE FOR SPARTAN 6 LX75 DEVICES WITHOUT CHANGE. TESTED ON TRENZ TE630 AND TERASIC DE2-115. OTHER FPGAs ON DEMAND. WHAT PYRATONE GIVES YOU:
Pyratone Sound Synthesis operates from 8 Hz up to 120 kHz with 768kHz sampling rate. For Audio, it is limited to 32kHz meeting the external sampling rate of 96kHz. Each single Key has it's own control set for oscillators, LFOs and ADSR-baviour. Altogether, there are 10 ADSRs + 16 LFOs + 6 HI-SCS running. This leads to 8192 Oscillators simultanously operating. In a larger FPGA the double number of modules can be implemented lead to 8 musical instruments. Sound Mix is performed with Phase and Amplitude based Room Placing in different ways. Several Options can be combined. The FPGA module offers 8 Outputs for Analog (PDM) oder Digital (DSD) data. Usually 4 PDMs are used to feed a double bass array with a HICUT at 400 Hz. Standard Digital Output is 8 channel S/PDIF and 8 channel I2S in parallel. All outputs are present simultaneously. WHAT YOU NEED: FOR CLASSICAL MIDI: AN INPUT AND OUTPUT CIRCUIT COMPATIBLE TO MIDI CURRENT LOOP PROVIDING INTERFACE FOR RX AND TX BOTH IN 3.3V @ 31.250 kHz FOR FAST MIDI 2000: AN INPUT / OUTPUT CIRCUIT COMPATIBLE TO S/PDIF PROVIDING INTERFACE FOR RXS AND TXS BOTH IN 3.3V RUNNING AT 48KHz x 64 = 3,072 MBAUD @ 6.144 MHz FOR ANALOG PDM OUT: AN ANALOG FILTER CIRCUIT COMPATIBLE TO 3,3V WITH A BANDWIDTH FROM E.G. 15 Hz to 25 kHz PROVIDING A GOOD REJECTION FOR FREQUENCIES > 25kHz FOR DIGITAL DSD OUT: A DIGITAL FILTER WITH RESAMPLING OPTION OR A DIGITAL DEVICE LIKE FPGA OR PLD COMPATIBLE TO 3,3V ACCEPTING DSD5x64 = 30,72MHz OR DSD25x64 = 153,6MHz FOR DIGITAL S/PDIF: A DIGITAL DEVICE COMPATIBLE TO 3,3V ACCEPTING 48kHz x 64 = 3,102 MHz BMC FOR I2S OUT A DIGITAL DEVICE COMPATIBLE TO 3,3V ACCEPTING 6,144 MHz BIT/DATACLOCK + 96kHz WORD CLOCK FOR PARALLEL OUT A DIGITAL DEVICE COMPATIBLE TO 3,3V ACCEPTING 192kHz / 24 BIT VHDL - CORES FOR SALE If you are interested in one of my VHDL Cores for Signal Processing, please contact me.
