Sequential Circuits Six-Trak OS v14 EPROM Firmware Upgrade KIT
- This version v14 is a custom firmware created by Tauntek that improves upon the last SCI issued v11 firmware.
- Included will be 1 new ATMEL EPROM chip, recently manufactured to ensure data integrity well past our natural lifetime.
- I do not use 35+ year old UV EPROMS that are prone to bit rot, a major cause of data instability with vintage equipment of this era.
Keep in mind that the Six-Trak itself is not for sale, only the EPROM upgrade chip will be supplied.
Unlike some others, No used or refurbished as “new” components will be supplied here.
- The aim of this custom firmware is to resolve software bugs and other issues some may have experienced with v11. Listed below are additions and improvements made by Tauntek:
- Patches can now be selected using the value pot. In Program Select mode, the value pot will now scroll through the programs as it is turned. Two ranges are used. 0-59 and 40-99. When the pot is turned two steps beyond 59, the high range is selected. When It is turned two steps below 40, we switch back to the low range. This may seem a little odd, but trying to cover the entire 0-99 range with the pot made the steps too close together and hard to control. Patches can also be selected using the keypad, as before.
- Unison detune has been added. To allow storing the setting with the patch, I used the Oscillator Fine Tune parameter to control the detune amount. If the patch does not enable Unison mode, or if MIDI mode 4 is selected, this parameter works normally. When detune is enabled, oscillator fine tune amount is set to 0.
- A new parameter (front panel #37 or MIDI #39) has been added. It is global, and is not stored with each patch. In fact, It is reset at power up. This parameter has three values, 0, 1, and 2. When It is set to 0, all voice LFO's behave normally. When It is set to 1, all voice LFO's are reset to the "no modulation" state when the voice is assigned. When It is set to 2, all voice LFO's are set to the "full modulation" state when the voice is assigned. So this parameter allows the LFO's to sync to the start of a new note. It can be controlled using MIDI, the same as other parameters, but there is only one of them, not one per voice. So all voices will have the same setting.
Be sure to take note of the marked orientation notch on the side of the EPROM to ensure correct installation. EPROMS inserted backwards will be destroyed. Incorrect insertion of ICs is also likely to cause damage to the board.
All EPROM upgrades have been prepared in an ESD-safe production environment and will be packaged in equally ESD-safe materials.
