ID	MatthiasIssueNr.	Issue release date	Issue	Solution
1	29	19.dec.2019	When mounting the matrix to the lower frontpanel by the ground terminals, a distance of 1 - 1.5 mm can be noticed between the matrix's surface and the frontpanel. Caused by the production charge of the ground terminals. In this charge the isolating upper bushing of the terminal is longer than usual. See the attached graphic therefor.	File down the narrow part of the bushing to at least 3 mm or less. Use a file or some sandpaper, a countersink will also help. Another option is to re-drill the matrix at these two holes to the diameter of 8.6 mm. Plan B: try a washer or 2 of them (not tested yet) Plan C: Re-drill the matrix at these two holes to the diameter of 8 mm and file down the tooth.
2	28	16.dec.2019	At the Z board there is a link missing on the 12 V trace. See the attached photo The failure affects OSC 1..
3	27	16.dec2019	At the Z board the captions of the presets are not printed.	See herefor the attached page of the population guide.
4	26	08.dec2019	"I meanwhile realized the EK construction manual gives no detailled information about mounting the matrix to the lower panel. So I decided to extend the manual by an additional page. Find this new page attached to this Newsletter. With this change, the actual EK construction manual now is rev. 1.24 and will be part of the next shipments (serial 078, 101, 106)."
5	25	04.dec.2019	PCB Version: Y19/09/mk4 cba There is no trace error at the X board. It is at the Y board - I am sorry. As reported, it was already soldered by Derek before packing the Electronics-Kit. But its good to check this one more time, as the soldered wire can be fallen off whilst transportation or handling.	Therefor see the attached photo. If this link is not present, solder a piece of wire to complete the trace.
6	24	03.dec.2019	There is a track error at the -9 V rail. Its at the bottom of the Z board area in the BACKPLANE !! See the attached backplane photo.	Solution: Solder a cable as shown in the picture (yellow link) to connect the right part of the -9 V rail. The upper panel is usually connected to the power rails by one of the 4-pin sockets in this area.
7	22	03.dec 2019	Info only: Please refer to page 2 of the Population-Guide Version 1.92	population guide_1.92_page2.pdf
8	--	23.dec 2019	Info: the 1K 2Watt resistor for the X board is for the PSU wiring... not on the X board pcb use 1% metal film resistors or select the 2% resistors on board X.
9	Issue 30	27.dec 2019	R 12 (PSU / earth link) The wiring diagrams were not correct since an update earlier. This causes a parasitic voltage and in some cases obviously a strange behaviour	Solution: Exchange the specific pages at your manual by the updated pages attached to this newsletter and follow these instructions. So the next shipments will include construction manual rev. 1.26 or even a higher revision. File: 2019 PSU issue.pdf
10	--	29.dec 2019	howto for X card remove the Pin 4 and 8 (the connector for the 2 TIp3055)
11	Patrick	Early 2020	use a 7mm drill that the flat screws fits flat on bottom of the PSU base plate, only as seen on the picture on right side. wide also the fuse holders with a 4mm drill that the delivered screws from the kit will fit thru the fuse holders.
12	31	Early 2020	Major Problem: At 110 - 120 V mains voltage, the primary wiring of the 115 V transformer causes problems on the secondary coils/outputs	Solution: Change the primary transformer wiring to the way, shown in the diagram attached to this Newsletter.
13	Patrick Issue	Summer 2020	Problem: the regulators are too hot for my experience - we waste too much energy in heat	the 18V AC transformer is "wrong" here - we have a 27V DC output after the bridge rectifier, beer we only need 15V DC. so I tried a 12V AC transformer which gives you a stable 18V DC output under load which is much better, the heatsinks are only at 22-30 degrees instead of 50C or higher. TME PART number: TS20/023 please note: you have to drill 3 holes in the PSU back plate to mount this.
14	Patricks	Summer 2020	Problem: Envelope bleeds in VCOs	the Lamp is the root cause. (updated 10/2024) look at Issue 21 !!! it can be replaced by a LED (preferred yellow) you also Need a 6V8 zener (6.8V zener Diode and cable tube/shrink) it was tested by me and works fine. TME Led holder with included LED: 2658.8073 (mentor vendor part nr.) 6v8 zener diode: BZX55C6V8-TAP
15	Patrick	07/2020	improvement: Buffer see bottom picture Paps offer buffer pcbs.. which means there's no voltage drop for the CV or Audio signal when you patch multiple sources and destinations ( 2x joystick to all VCOs Freq. for example) see above pictures.	http://www.portabellabz.be/synthipcbs.html Install. guide: buffers.pdf
16	Patrick	11/2020	general info about the wiring	100meter (roll) BKL Electronic 1509008 available by voelkner and conrad.de few meters are supplied with the cloney kit, but it was´nt enough on my builds.
17	Patrick	11/2020	Powersupply change click to enlarge	I removed the Internal Powersupply - transformer to have less hum and EMV in the reverb and circuit. And we don't want Main Power handling for people who don't have the knowledge - its forbidden in some country to "play" with Main power. My solution is to use an external Yamaha PA-30 PSU (available in 110V and 230V). the wiring must change too. Things you have to change: remove the IEC and order from Schaeffer or Frontpanelexpress following part: vcs3_power_ext.fpd 2. Install the above Panel in place of the IEC socket and install there a CLIFF FC684203 3. install a DPST switch (the original Lower Panel Powerswitch is a SPST) 4. connect PIN 1 and 3 of the Cliff connector to the DPST Switch, the switched outputs goes to the Fuseholder 5. Pin2 of the Cliff jack is the Ground, which has to be connected to the CN groundbus. 6. we don't need anymore the 1K resistor at the bottom Rail, we use just one STAR ground connection.
18	Patrick	11/2020	Matrix Change	I have an Ghielmetti Matrix installed, with some modifications you can install an Edge Connector for Prestopatch cards. Here's the Frontpanel Designer file for the Pinpark cutout, feel free to change it. change in the panel the thickness to 3mm !!! File: vcs3_2_5mm_rad_neu.fpd
19	Patrick	11/2020		you can order this from Ponokko or Formular for 42Euro 3mm clear Acryl Glas
20	Patrick	11/2020	CV- GATE Interface the Connectors on left and right side to the Interface are still usable	http://www.portabellabz.be/cvgate.html Manual: cvgate-manual.pdf BOM: CVgate_Card_BOM.xls some Parts from Reichelt (I don't have a full list) Trimmer: 64W-100K Diode: BZX 55C5V1 VIS (5.1 zener) 4x 3.5mm socket CLIFF FC681374V 2x NK236 Slideswitch 2x LM741CN 1x MKS2-50 680N.

21	Patrick	10/2024	Lamp in Off mode isn´t off - This minimize bleeds to the VCO too	connect one end of the Lamp with a 2K2 in series to 0V (GND) and not as before to -9V 2. connect the other end of the lamp as before on the wiper pin 3. connect a 2K2 resistor between CN24/3 and the potentiometer the picture is from the Synthey Build.

Calibration (the better Version)

Start with PSU, then Output Filter - the Output Filter

Power Supply

Before turning on, set PR1 cw and PR2 ccw with only ‘A’ board plugged-in.

Set PR2 for +12V ± 0.1V Set PR1 for -9V ± 0.1V

Check PR2 again and reset if necessary

N.B. -9V rail is parasitic on the +12V supply.

Plug in ‘B’ and ‘C’ cards and recheck +12V and -9V rails.

These should not have altered. If they have, suspect either ‘B’ or ‘C’ board orpoor regulation on A board. Plug-in keyboard as extra load. +12 and -9 Volt rails should not have moved more than ± 0.1V measured always on the ‘A’ board. (‘C’ board voltage may be 20 mV lower)

Monitor the rails on the scope (5mV/cm). Look for hum and noise. These should be much less than 5mV. Noise, if present, will probably be due to the zener diode.

Power supplies should stabilise on full load for specified fluctuations.

110/240 nominal : +10% or -23%

110 nominal : 100V-135V for 125 sufficient

240 V nominal: 200V-260V

Hum can also be checked by the following:

Check Output Filters on 10 Output Controls on 10.0.10.10

Patchboard vacant

Monitor (5mV/cm) on signal output

Load unit with keyboard

100 Hz ripple as shown.

Noise can be seen which should never exceed lOmV p.p. Even with noise

level up. With noise level down, the noise on this waveform should be

quite low. Zener diode noise will be very obvious.

N.B. A2 normally gets hot, dodgy Dl gives large 100Hz ripple on Output. Always clean edge-connectors and check clean presets on ‘A’ board.

Click to expand: Output Filter:

Output Channels

Set Output Channel Filters to 5.
Set Output Level row to 0.0.10.0 and connect traces of scope (5mV/cm)

to both signal outputs.

Connect full level ramp signal at 261 Hz from Oscillator 1 to both Outputs.Trim PR4 and PR5 for minimum signal breakthrough. (Maximum 5mv p.p) Replace presets if adjustment is erratic.

Reset Output Channel row controls to 5.0.10.5. Output levels should be around 1V p.p and should be within 20% of each other. Check signal tracking in thesame manner for Output settings 4 and 6 as well. If one level is consistently high, pad out resistor across its control pot (R305 = 56K)

Successful tracking will depend on the characteristics of the pots and the correct matching of the FET’s Q14 & Q18.

Connect the joystick row via two shorting pins to both VC level inputs. Swingstick up and down to check for 20% level tracking tolerance.(Level pots shouldbe at zero). Inaccuracies in stick tracking may be adjusted by altering thevalue of R302 or R304 (lOK) which are mounted under the patchboard rear.

Check correct operation of Pan controls, which only affect the Signal Outputs. Check also the Output Filters. Use noise as a good source.

Check for max. outputs on the Signal Output socket of at least 2.5V p.pbefore the onset of clipping. Level controls should be at about 6. Checkheadphone signal is good. Check for instability of Output Amps by driving hard with low frequency. (Oscillator 3 square wave). The level control of thechannel NOT being driven should be on zero. Monitor the two signal outputs.The undriven channel will show breakthrough. Plug in headphones and check for oscillation. Reduce drive to Output Channel 2. Keep checking for oscillation.Then repeat for other Output Channel.

N.B. DC offset across loudspeaker is 1.8V ± 10%.

Reverb

Reverberation

Set PR3 fully clockwise before operating. Feed large amplitude tone bursts into reverb. Adjust PR3 so that the output is dry at Mix setting of zero and reverberation progressively increases from setting of 2.

Maximum dryness on the Mix control should be no worse than thatobtained with the VC Mix input row on the patchboard grounded.

Check voltage control of Mix with the joystick.

Hold input amplitude constant and sweep frequency of tone. Check for rattles, buzzes or abnormal resonances in the spring. Check spring is correct way round. If Mix control is wrong change Q10.

N.B. Reverb amplifier should clip symmetrically.

Click to expand

Envelope Shaper

Put scope on 2V/cm and connect to Trapezoid output. With envelope controls at 0.0.0.0. Adjust PR12 so that frequency of trapezoid oscillation is about 90% of the maximum possible frequency. Connect Filter output on 261 Hz (Frequency setting 5) with maximum output to Envelope Input, Monitor Envelope output. Set PR13 clockwise.
