Musical devices and sometimes artichokes are being discussed here

TR707 TR727 reset, midi out, tricks etc

Reset your TR707 or TR727 to factory settings.. here is the buttons combination to give your drum machine a fresh new start and to check leds and screen, buttons.

Keep pressed CLEAR and INSTRUMENT/GUIDE and switch on the legendary (yes, legendary) drum machine.

All the lights will turn on, then step leds will blink one by one.

After the light show, press ENTER/CARTRIDGE to proceed with the screen test.

Press the buttons and see the relevant dots show up on the screen.

Switch off.

How to use the TR707 or TR727 to output midi notes, and use it as a midi controller to play other midi modules, samplers (bear in mind its defaut midi channel is 10):

STOP the pattern/track if it is playing.

Enter TRACK PLAY mode.

Holding SHIFT press INSTRUMENT/GUIDE and MIDI CHANNEL.

This procedure will mute the instrument’s internal sounds but will allow you to control external gear using the TR707 or TR727.

To revert back to default, using the internal sounds but NOT transmitting midi notes, and if you have a TR707/727 that is silent, just use the same keypresses again.

Common troubles with these machines:

PSU jack fail, power transistor 78M05 (can be substituted with 78S05), power supply section electrolytic caps.

Dim screen=check the power supply section.

Try different psu transformers too: Roland’s own are recommended, etc

These are machines that heal themselves.. put them aside for a while or leave them turned on for some time and they will fix themselves.

Maybe.

Roland CR8000 buttons repair made easy

Roland Compurhythm drum machine CR8000 with faulty or worn buttons.

Sounds a lot like the TR808, but a design fault makes these buttons useless after a while.

You need to pull the plastic covers first, to reveal the spring and rubber dome under which we will drop a bit of conductive paint..

To pull the plastic part you need to push the sides using a screwdriver or two like on this video:

SammichSID Novation Zero SL mkii template

Those geniuses at Novation shipped this controller with a couple of software disks but alas, no TEMPLATE EDITOR for people who dont use a pc to make music.

Download the template editor program from their support pages, connect the Zero SL to your pc via usb, switch it on and fire the software. Press Global options on the SL, choose mem protect off.

Load the syx file provided by yours truly:

Masuto’s SammichSID template 😊

and then.. select

Press Write, and bob’s your uncle.

I saved it in location 20 (empty) and made it the startup template.

For your reference, heres a crudely PAINT assembled wildcard:

Happy knob twiddling!

Akai S612 sampler

I opened my newly acquired Akai S612..to check for spiders and animal residue from its previous owner – i was intrigued by the “cassette interface”. Mine was screwed behind a closed metal door.

I realized right away it is the same cassette port as the Commodore 64.

And yes, you can save, verify and load your samples using an old (non)trusty tape Datassette!

I sampled a sound, got some tape to record, went fast forward 004 counts on the tape counter, pressed rec and play and then pressed save on the Akai panel. Red light, it’s recording.

Counter reading 044, the Datassette automatically stopped. I rewound the tape, switched off the Akai (remember with these old machines it is better to switch them off before plugging or unplugging devices from serial ports..), on again and Load. Pressed play on tape, and yes. It’s working. Easy.

No need to buy the MD280 rack to load discs on the S612.. you just need a Commodore Datassette (clean its heads and fix azimuth before doing anything)!

MAM/FAT 383/FREEBASS 303 simulator guts

A couple of gutshots of the 303 simulator (cannot call it clone since it doesnt have a BA662a..)..

Some kosher transistors (1583, 2291) but most of them are just 2N3904.

Sounds quite good.. i remember staring at the Turnkeys window in Charing Cross Road (98?) when these came out, along with FAT’s other offerings, rebadged MAM, like the cool resinator (the resonator) and some other rack in sexy colors!
