12 frequencies of the highest required octave appear at itsoutputs (see Fig. 12). Therefore, the nameTop-Octave-Synthesizer (TOS) describes the functions of thisIC. Due to the mathematical relationship between neighboringtones of an octave the IC often is called a Twelfth-Root-TwoDivider. The frequency at output "A" for example is 7040 Hz.4.3 Frequency DividersEach output of the TOS is fed to an integrated divider IC 1. Itdivides the incoming frequency 7 times by 2. There is anoutput after every divider stage. This means that, besides thetop octave tone, 7 lower octaves are available too. Forexample, the IC 1 (A) generates the "middle A" (440 Hz) after4 divisions and 55 H z after 7 divisions.The outputs of the TOS as well as all divider outputs areconnected to rows of pins which are sequentially numberedfrom 13 (CO = 32.70 Hz) to 108 (B7 = 7902 Hz)The output signals are square waves with an on/off ratio of1:1. The "on" state corresponds to ground potential and the"off" state to -15 V DC. The output signals control the analogswitches on the plug-in boards (see "Gating Cards G 2 ").The outputs of the top octave are also connected to the pins P97 to P 108. There the 30-pedal electronics will be connectedwhich has its own frequency dividers.The 13-pedal electronics will be connected to the pins P 73 toP 85 which are fed, via the diodes D 1, from divider output(two octaves below top). The 13th required frequency is takenfrom a higher octave and connected to pin P 85.4.4 Frequency StabilizationSuppose that the inverting input 6 of op amp IC 5-B alreadyreceives a certain constant control signal. The output 7 of IC5-B, therefore, assumes a certain potential (between + and -15V DC),such that transistor Q 1 has a certain resistance which,in turn, determines a certain oscillator frequency.The highest output frequency of the TOS (output 108) is fed tothe input 5 of inverter IC 3-3. IC 3-3 merely serves as a bufferbetween the TOS and the control loop. The square wave signalat the output 6 of IC 3-3 is differentiated by R 6/C 2 andrectified by D 3 and D 5. The resulting control current is fed tothe inverting input 6 of the o p amp IC 5-B.This closes the feedback loop. The automatic frequencystabilization can be described as follows: The oscillatorfrequency increases - the frequency at the output 108 increases- the differentiated pulses on C 2 follow each other at shorterintervals - the current into the input 6 of IC 5-B increases - thevoltage at the output 7 of IC 5-B decreases - the "resistance"of Q 1 increases the oscillator frequency decreases.The capacitors C 4 and C 10 eliminate any residual ACvoltages on the control signal.The input 6 of IC 5-B also receives the control signals from allother circuits.4.5 Master Pitch ControlThe external control "Master Pitch" is connected betweenground and -15 V D C. The maximum potential shift of 15 Von terminal B 6 results in a very small control current throughR 48 and R 30 to the input 6 of IC 5-B, producing a pitchvariation of approximately a half-tone. We assume that thepitch control be at its mid-position for the followingdiscussions.4.6 Slalom/Tuning low/Tuning highThe potential at the tie point between R 28/ R 42/ R43/R49 isdetermined mainly by the voltage division of R 28 and R 49 +"Slalom" control. The most positive value exists if theresistance of the "Slalom" control is zero (left-hand stop). Thesaid tie point is then almost at ground potential since R 49 ismuch smaller than R 28.The resulting control current through R 43 and R 30 pushesthe oscillator frequency downwards. Simultaneously, the trimpot P 1 (Tuning low) and the position of the analog switch IC4-1 become ineffective.This (low) frequency is adjusted by means of trim pot P 2 suchthat the highest "A" (output 106) assumes a frequency ofexactly 3520 Hz. Note, that the master pitch control remainseffective.If the "Slalom" control is moved to the other stop (= 100kOhms) the potential at the tie point R 28/ R 42/R43/R49becomes more negative; the frequency increases. The exactvalue is adjusted by trimpot P 1 (Tuning high) such that thehighest "A" (output 106) is equal to 7040 Hz. This calibratesthe "Slalom" control, that is it enables it to shift the pitch ofthe entire organ by an exact octave.The transposer can be connected to pin B 7in lieu of the"Slalom" control. The transposer consists of a switch whichselects a series of precision resistances replacing the "Slalom"control. The "high" toning is shifted by one or more half-tonesteps (see Fig. 9).
