TuBika (formally known as Ambika) is a six voice poly DIY ( do it yourselve) synthesizer.
Here you get all parts and PCB‘s you need to build/solder it yourself.
The concept behind TuBika are digital oscillators in combination with analog filter‘s and VCA‘s.
Four Filtercards with different flavors are available. 4P, SMR4, SVF and ladder.
You can combine different voicecards. 6x multi mode is also possible.
Each voice had it‘s own ARP and Step-Sequencer.
Maximal six voice polyphon , MIDI controlled.
Available filterboards are
four different filterboards/voicecards
All filterboards have it's own flavor .
I suggest you to use for poly play 6x the same Filterboard or 4x the same and 2 different
A good combination is 4xSMR4-Plus and 2 differenf Filterboards like 4p and SVF or SVF and Ladder .
the default filterboards in a complete kit are 6x SMR4-Plus , usefull for all kind of Music

You can also select your filtertypes. Same price for SMR4-plus, SVF, Ladder or P4.
Default and good sounding filter are the SMR4plus - usefull for all kind of music
I recomend 4 x the same voice - SMR4 for example and 2 different filter like 1x Ladder 1x SVF or 4P.
If you want to play only poly you should use 6x the same filterboards , SMR4-plus for example.
Building time : motherboard 2..3 hours , each Voicecard 2 hours, adjustment and case mounting 1..2 hours.
Building time means solder the parts , clean the PCB , check all parts again , solder points are OK ??
mesaure the Voltafge on the testpoints and so on . We are not in a race . Good mounting take its time.
