the a-100 basic system 1 is a reliable starting point for working with the a-100 but it contains no midi interface. you need an external midi-to-cv/gate interface or cv/gate keyboard :

2x standard vco a-110
2x adsr a-140
2 x lfo a-145
1x ring modulator a-114
1 x audio divider a-115
1 x vc waveform processor a-116
1 x noise/random a-118
1 x vcf1 a-120 (24db low pass 1)
1 x xp vcf a-106-6

remark: the earlier used 12db multimode filter a-121 has been placed in the basic systems from january 2010 by the a-106-6 xp filter. the production of the a-121 had to be stopped because of the no longer available special circuit cem3320

1 x linear vca a-130
1 x logarithmic vca a-131
1 x linear mixer a-138a
1 x logarithmic mixer a-138b
1 x dual s&h a-148
1 x dual vc switch a-150
1 x trigger divider a-160
1 x trigger sequencer a-161
1 x dual trigger delay a-162
1 x dual slew limiter a-170
1 x multiple i a-180
30 patch cables (mixed)

the modules of basic system 1 are assembled in a 6hu frame with built in power supply and bus boards. the 6hu frame is also available without modules to configure an individual system or for expanding the basic systems with additional modules. the purpose and function of other modules will become more apparent as you work with your system, and you will be able to decide which extra modules you need for your particular purposes.
