DRUMMIX II - A Drum Computer in VHDL on a Xilinx Spartan 6 FPGA

Spartan 6 based drum computer
	128 oscillators 32 voices 128 midi channels 96 kHz Audio DSP Sound Demo 1 Sound Demo 2	A complete drum and rhythm machine in VHDL This page shows version 2 of my FPGA-based drum computer. For technical details regarding VHDL and base board see page 1 of the article Spartan 6 drum computer 2012. Changes: 64 virtual voices using 2 in parallel for 32 channels 768 kHz sound generation enhanced 92 kHz Audio DSP processing Echo, Reverb, Vibrato and Tremolo Enhanced Virtual Console RS 232 @ 460 kbaud Direct XSVGA output of settings and parameters with real time spectrum analyzer oscilloscope like output during wave design enhanced midi memory enhanced song memory enhanced beat morph system Spartan 6 LX FPGA System . A Spartan 6 FPGA board from Trenz Electronic Germany is used for sound synthesis and video generation. 2 PS/2 ports (mouse + keyboard) are available for graphic and synthesis control. Also a MIDI-controller can be attached: The DIY-MIDI-Controller works with standard 4x230kBaud, which is about 25 times faster than normal MIDI. See the MIDI 2000 page for details about my MIDI standard. MIDI Controller Drum Computer Front To control the FPGA directly certain functions can be accessed by internal rotary encoders. Here no LED feedback is used but the values are represented on a SVGA output. There is a drum computer GUI as well as a GUI which shows directly knob positions. Therefor the screen of the front plate is used. Drum Computer PC GUI Drum Computer Knob Representation, now with smaller keyboard but more knobs than in version 1. It has a 16 step sequencer for each channel and individual tone control for tuning the sounds in real time. As an example bass drums and toms can be configured with the right frequency to met the melody's tuning perfectly. Song and pattern programming is performed via GUI or PC upload. Construction Details Data Flow and interconnections of the drum computer 3D-View of the mechanical design of the drum computer Current realization of the drum computer using Mentor knobs for the encoders: Listen to a demo drum song of the DRUMMIX 2: Mix1 Listen to a demo track with simple drum sounds together with the Pyratone FPGA Synth Engine : Mix2 The Drum Computer shows also internal settings and values like wave synthesis and levels via a virtual MIDI knob matrix: Programming Screen of Drummix 2 The Drummix in version 2 again uses the formerly invented beatmorph method to resample and retime stored samples and morph in between them thus making it possible to modify the complete sound seamlessly in real time.
