Add to your order: ATS-55250W-C1-R0 (from the) its a 1inch cooler for DC-DC PSU (read the issue list) 17.Nov.2022
the Mouser project can't be shared anymore, its the best that everyone create a own to their requirements.
too much parts are out of stock and its highly recommend to order by other shops too.
Tme.eu is a good place for European users. (EU)
other sources are digikey, Distrelec, RS, farnell, reichelt, Conrad, Uk-electronik, banzai (call the guys about the stock), thonk.
here´s an excel with some parts which I ordered by tme (it doesn't include all- but some parts are here much cheaper and in stock)
TME-order-ISE-NIN-partial!!.xlsx
some notes:
the tactiles are out of stock by mouser - use tme.eu or other supplier.
for the 3900pf caps, you can use polypropylene caps
use eBay or tme for the SMT caps to safe money

Info ID | Date | Location | Type | Issue | Tip | |
---|---|---|---|---|---|---|
1 | 13. Aug.2022 | Hardware Board | INFO | minimize Slider/Potentiometer malfunctions Soldering Info | when you install the sliders, DO NOT solder all pins successively, solder only one pin at the top and the bottom and proceed to the next slider, when you have installed all of them - solder the next single pin of each slider. this has to be respected with potentiometers too. The Sliders and Potentiometers have lubrication inside which is sensitive to heat and can be easily damaged (this mistake was made in many Syncussion clones ) | |
2 | 13. Aug.2022 | Hardware Board | INFO | OLED Selection and R101/R32 - R100/R102 | when you have an OLED with the PINOUT: VCC-GND-SCL-SDA install R100 and R102 (0 Ohm - a bridge) (R32/R101 must be left empty) in case you have an OLED with the PINOUT: GND-VCC-SCL-SDA install R101 and R32 (0 Ohm -a bridge) | |
3 | 13. Aug. 2022 | All pcbs | INFO | some IC Sockets do not point in the same direction as the others, it´s a known issue that people install ICs backwards | Double and triple check every IC orientation - maybe 80% of all device malfunctions happen because of that and often end in very expensive repairs | |
4 | 13. Aug.2022 | Hardware Board, PSU, Mainboard | INFO | the LEDs do not work | when you build the device - its important to start with the power supply - here you can test the LED orientation. never trust the vendor pinout for LEDs. normally the long LED leg is the positive end (anode) (but some circuits are powered from negative rails and GND is the positive end in this case- just as an explanation) | |
5 | 13. Aug. 2022 | Mainboard | INFO | solder the pins on the Edgecard holder where you find the white stripe on the PCB - | you can't install the edge cards in the wrong way | |
6 | 14.Aug.2022 | Mainboard | INFO | keep the length of the power cable as short as possible - that minimizes the risk that you accidentally put the PSU card in a voice card slot | ||
7 | 14.Aug.2022 | Hardware Board | INFO | pay attention to "Pot23 - Volume" (upper right corner) this is the one non-center detent pot. | ||
8 | 14.Aug.2022 | Mainboard | BUG | BOM1.0 Change- fixed in BOM v1.0.1 R103, R104, R105 = 330K (was 30k in BOM rev 1.0.0) R128, R143 = 10K (was 30k in BOM rev1.0.0) R137, R146 = 10K. (was 20k in BOM rev1.0.0) | fixed on 24.Sep.2022 in BOM 1.0.1 | |
9 | 03.Oct.2022 | Parts | INFO | the 2N3094 on the Voicecards must be a matched pair (within 2mV vbe) | A. if you are a pro builder.. you still have a device to match trannys. B. you can order or build a tester C. you order matched pairs by me or thonk https://www.diysynth.de/diy-components/aktive-bauteile/gematche-transistoren.html?language=de | |
10 | 18 April 2023 | PSU | BUG | R8 220R on the PSU goes very hot - it affect the lifetime of this part | workaround: change to 2Watt 220R 1% resistor metalfilm or try 470R 0,6watt 1% metalfilm a solution or other workaround is in test (TL431 source from the 5V regulator instead from 15v) |
first test on a bench PSU with current limit
Start with the SMT parts on the rear side and IC4.
here´s an example how this has been installed by me, add some solder on one pad and heat up this pad while you move a capacitor with a tweezer to the location, then add some solder on the other side too, normally no extra flux (fluxpen) is needed but depends on your skills.
the heart of the ISE-NIN must be build really carefully !!
you need an ESD map and ESD safe handling (tools) - because the uController is preinstalled and can be destroyed due to wrong handling.
I really prefer to use a Soldering frame - Ideal Teck PCSA-4 (the MB and HB-pcb fits perfect)
do not install the 10pin headers/pins yet (we put the header on the pcb later - when we have finished the controlboard - to get the best alignment)
Hardware Board (HB) (sometimes called Controlboard)
do not install the OLED yet - to avoid damages and dust on the screen
do not install the headers /pins yet
do not install the LEDs yet, no sliders , no potentiometers for now !!
because you have to clean/wash the PCBs before we can proceed - jump to Voicecard assembly until the pcbs are dry. (normally overnight in a warm room)
assemble the voices until the other pcbs are dry - do not install the trimmers until you have washed the PCBs!
finally we can move to the last steps which can be done in different ways
9. install the tactile switches and solder these, solder 1-2 per switch - not all pins together to have less heat on the part.
10. the last parts can be installed with one step or step by step - but in this case, you have to remove the frontpanel a few times. (customers with experience from DDRM/Kijimi can try to install the pots, OLED, LEDs, tactiles and the tactile caps in one step)
11. cut/remove the locker pin on the potentiometers
12. the potentiometer must be installed with the front panel attached for best alignment - please note: one Potentiometer is not Center detent !! its marked on the pcb without an line in the circle.(volume pot)
13. the potentiometer have to sit on the pcb - do not try to to install the potentiometers in a higher position (or you can run in problems with the knob height)
14. there are 2 options how to do that.. but my shown option should be the best with separate nuts (no wobbling pots)
DO NOT try to install the nut on the frontpanel side !! install a nut as shown below .
15. OLED - install 2x M2 5mm Spacers on the OLED (you dont need 4 spacers) and respect the pinout as described in the Information List ID2 - its important to double check the pinout and measure the GND pad of the OLED against other GND pads on the HW.Board.
be careful with the OLED !!
LEDs:
here´s an example how to install the LEDs easily:
Put the HW board on the Mainboard:
install the spacers (12mm spacer between HB and MB) put the MB on the HB - then solder the headers on the pcbs
mount the bracket on the BB pcbs with 2 screws.
We use MTA156 headers which can be used with cables of 1.5mm2 maximum.
the current is 1300mA at 12V under load, cable length is 0.5m max.
A = ( I x 0,0175 x L x 2 ) / (fk x U)
result is 0.75mm2 for 1m is safe !
(0.5mm2 is fine too since I used in my calculation 1meter and 2Amps)
Test the PSU without BB - on a bench psu with current limiter 250mA only the PSU.
with mainboard connected 1000mA (without Voicecard)
with one card try 1000mA- with all cards up to 2.000mA
The OLED and LEDs will only work after you have installed the Firmware !! (some leds are on without the firmware)
The latest Firmware and install guide is on a separate page : ISE-NIN Manuals and Firmware
Instructions for Calibrating
• First, put all CENTER DETENT pot / sliders at center, |
after 30 min of warmup go to the MENU, CALIBRATION, VCO CALIBRATION, press run. |
Here is a step by step guide to calibrate the filter resonance: (ONLY AFTER that you need to calibrate filters in further step)It´s recommend turning the resonance trimmer TR1 fully clockwise on each voicecard to make this procedure as easy as possible! The best way is to use 8 resistors on the mainboard for making a measurement. 1. Warm up your unit about 30-40 mins 2. turn on ISE-NIN, Go to menu (press shift (grey cap button) + Back (middle button under the display), then calibration, choose CROSSMOD then press SHIFT and press the encoder, this will add the hidden RESONANCE and CROSSMOD TRIM function (its hidden since prebuilt units do not need this) (The display should read: "card 1" and you should hear a test tone through the outputs (for the next voice card you can press the "next (Back)" button to cycle through the voice cards) 3. Connect a Scope probe on the Mainboard, to the resistor of the card which you calibrate , set your oscilloscope to "timebase 0.5ms/cm" and "1V/cm" (on DMM: 0.5V -1V is fine too, depends on your scope screen resolution - some new scopes are HD resolution in 720p or more and the ADC are very accurat) 4. You should see the filter signal on your scope. If you have turned the trimmer fully clockwise the signal should be- and sound distorted. now turn the "resonance" trimmer TR1 on the Voicecard anti- clockwise until you get a clean signal as in the picture below (The difference of maximum and minimum amplitude in one cycle has to be 4-times.) make sure to have enough gain otherwise the Filter calibration step will fail as described in next section. Comment from Black Corp: "We especially made all settings in resonanse calibration how they should be (square, cutoff, 12db etc)." Congratulations, you have successfilly calibrated the filter resonance for all of the voices! Resonance calibration Method according to the Roland Jupiter-8 service manual (not recommended yet → use above method!!!):Go into MENU, CALIBRATION, RESONANCE. Follow these steps from the Jupiter 8 manual, turning Trim1 for each voice (or see below): Workaround or turn Trim TR1 until the self oscillation is off on each voice. you can switch between the cards using the switch button on the mother board. |
you have to finish the resonance calibration before you proceed further with this step but read the Help in this section, to avoid problems. Go into MENU, FILTER, CALIBRATION, press "run" (push the encoder or enter by a pushbutton) Help: in case the Frequency stuck at "37Hz" or "no Signal" is on the OLED shown, you have to turn the resonance trimmer clockwise to have more gain - your resonance calibration was wrong. if you still have issues, look in the Troubleshooting page Technical Background: some filter designs have the possibility to make sounds byself, the Filter can act as a Oscillator (for example percussive sounds or bass drums). Since we have a oscillator function in Filters, we can control them v/oct based for example, that's what we calibrate automatically in the ISE-NIN filter calibration method. the Frequency Calibration is a V/Oct based Modulation which use the Filter Oscillation signal (resonance), the ISE-NIN calibration software need this signal, only with enough gain it can be analyzed and . |
Respect the Cross Mod TRIM vs Cross Mod Calibration - this steps must be in the correct procedure
MENU, CALIBRATION, choose CROSSMOD then press SHIFT and press the encoder, this will add the hidden RESONANCE and CROSSMOD TRIM function (its hidden since prebuilt units do not need this)CROSS MOD TRIM, connect USB out of ISENIN to computer, turn on ableton select ise-nin as input, put a tuner oh the channel and adjust it to 220hz with the Offset Trimmer for each voice, switch between voices with the switch button. |
Go into MENU, CALIBRATION, CROSS MOD CALIBRATION, press run |
