here is the completed table of the parameters for each patch. Patches start in the static RAM at location 2200h and use 21 bytes (15h). So all 64 patches fit into the memory range from 2200h through to 2740h. In the table below, the columns are bits within each byte and the rows are byte numbers.

	7	6	5	4	3	2	1	0
1	X	DCO2 wave sqr=0,tri=1	X	DCO1 wave sqr=0,tri=1	DCO2 Octave (00-01-10)	DCO1 Octave (00-01-10)
2	DCO2 2'	DCO2 4'	DCO2 8'	DCO2 16'	DCO1 2'	DCO1 4'	DCO1 8'	DCO1 16'
3	Chorus On=1, Off=0	MODE Double=1, Single=0	X	X	X	X	Detune 0-3
4	Noise Level 0-15	DCO Interval (0-12 decimal or 0-0Ch)
5	DCO1 Level Bits 4,3,2	VCF Polarity	EG INT (0-15)
6	X	DCO2 Level Bits 0-31	DCO1 Level Bits 0,1
7	VCF Trig M=1, Single=0	VCF Cutoff 00-63h (7 bits)
8	MG Delay 0-15	MG Frequency 0-15
9	MG VCF Depth 0-15	MG DCO Depth 0-15
10	DEG1 Decay Bits 2,1,0	DEG1 Attack 0-31
11	DEG1 Slope Bit 0	DEG1 Break Point 0-31	DEG1 Decay Bits 5,4
12	DEG1 Sustain Bits 3,2,1,0	DEG1 Slope Bits 4,3,2,1
13	DEG2 Attack Bits 1,0	DEG1 Release Bits 4,3,2,1,0	DEG1 Sustain Bit 4
14	DEG2 Decay Bits 4,3,2,1,0	DEG2 Attack Bits 4,3,2
15	DEG2 Slope Bits 2,1,0	DEG2 Break Point Bits 4,3,2,1,0
16	DEG2 Release Bit 0	DEG2 Sustain Bits 4,3,2,1,0	DEG2 Slope Bits 4,3
17	DEG3 Attack Bits 3,2,1,0	DEG2 Release Bits 4,3,2,1
18	DEG3 Break Point Bits 1,0	DEG3 Decay Bits 4,3,2,1,0	DEG3 Attack Bit 4
19	DEG3 Slope Bits 4,3,2,1,0	DEG3 Break Point Bits 4,3,2
20	DEG3 Release Bits 2,1,0	DEG3 Sustain 4,3,2,1,0
21	VCF Keyboard Track 00-01-10	VCF Resonance 0-15	DEG3 Release Bits 4,3

Writing a patch editor for the EX800 is going to be a piece of cake.
