Fans of the classic and hard to find Roland TR-909 drum machine are about to have their worlds rocked. Today E-licktronic, the maker of the Yocto Roland TR-808 clone, teased the Nava v1.0, which they describe as a “1:1 clone of the analog section of the Roland TR-909.” Nava v 1.0 will be sold as a DIY kit with all rare transistors and ICs, potentiometers, switches and preBurned µC. The Nava kit is expected to be available April 25 for €319,00. The Mouser part is priced at US $183.73. Case cost is TBD. The kit includes:
2 x PCBs: the Mainboard and the IO Board
The µC, a Atmega1284P pre programmed with Firmware Nava v1.0
3x program EPROM 27C256 with the sound of HitHat, Crash and Ride as those present in the original TR-909.
36 x M5218L Mitsubishi. Those are the origianl TR-909 OPA
2 x HD14006BP 18 Bit static shift register used to Noise generator
1 x AN6912 Quad comparator. HandClap envelop generator identical to that of TR-808.
1 x BA6110. This is the only component that we have replaced the original TR-909. The original HandClap VCA is a BA662 manufactured by Roland, but today very expensive and rare. After several sound comparisons and operating the BA6110 makes an excellent substitute for BA662.
19 x 2SA1115-F PNP transistors
56 x 2SC2603-F NPN transistors
4 x 2SA798 PNP Monolithic Transistor Pair
2 x 2SD1469 NPN Small signal transistor
2 x 2SC2878 NPN Epitaxial transistor for muting application
27 x Potentiomètres Potentiometers (all necessary controls for the construction of Nava v1.0)
19 x Cherry switches with whites caps
17 x illuminated square tact switches
All other components to complete your kit are available in this Mouser BOM. The only component that you must get is a 15VAC supply 1000mA, the same used for the Yocto v1.0. A screen printed aluminum case will soon be available on the forum.
Characteristic of Nava v1.0:
128 Rhythm patterns from 1 to 16 steps
16 tracks of 999 measures
1 external instrument track by pattern that can store 99 notes like SH101 sequencer style.
A Midi keyboard mode allow you to play external Midi device
Multi out for each instruments
Individual accent for BD, SD, LT, MT, HT, RS, HC and CH
A total accent track
Master out (L/R Mono) 6Vp-p 1Kohm
tempo 30 – 250 Bpm
7 shuffle levels
4 scales (1/8t, 1/16, 1/16t and 1/32)
4 sequencer directions (forward, backward, ping-pong and random)
Easy copy and paste pattern function
Shift left or right the entire pattern or individual instrument
DinSync 24ppqn Out
Trig Out 2ms +5V
I’ve been working at getting all the components ready for the Nava build, and the only item left is the metal box and it’s due to arrive at my house any day. I’ve built two Yocto’s (808 clone) and I’m really excited about the Nava. 7/22/2016
