Roland TR 330
Roland TR-330 (late 1972 / early 1973 ??)
This is a bit of an odd one with respect to the name. It's pretty rare too. The TR label belies its roots - it's from the Roland family of Transistor Rhythm Machines.
Did Roland base it on the TR-33 and add a zero - thus TR-330 ??
She probably lies between the TR-77 which came out in 1972 & the TR -66 which was first manufactured in 1973. (It's definitely not as advanced technically as the TR-66 which is why I think it comes before the 66 & after the 77).
And I think it sounds a lot like my TR-77 too.
Take special note of the wooden cube shape. The 330 was the first of Roland's drum machines to take this appearance which would finally evolve into the ground breaking CR-78 in 1978.
There is heaps of bass and great analog percussion - claves etc. There are 8 drum sounds.The Kick is very very good. Reminds me of my TR-808. Lots of bottom end.
The voice board has trimmers (variable resistors) for tuning the oscillator's pitch & resonance....and/or for some very nice distortion. Nice warm & round analog sounds.
The circuit boards & speaker slide out of the wooden sleeve very easily They are held in with just 4 screws on the bottom.
And it has it's own built in speaker which you won't find on any other Roland drum of this vintage.
The speaker isn't of the highest quality but if you like rather cheezy distortion you will love it.
I don't have any service manual or schematic so if anyone out there has one I'd be forever grateful.
The tempo slider is unusual. It displays the tempo both in modern BPMs (40 to 280) and in the traditional classical way ..... in Italian, as was the custom before the invention of the metronome.
The old way is def more romantic. Largo (rather slow; stately), andante (walking speed) & presto (Very fast) are words you rarely see on a drum machine.
There is one "Balancing" knob which sets the volume of the Kick & Hi hat. It can completely mute the hi-hat or totally remove the kick which I think is very useful.
There are 10 Preset patterns. Waltz, Slow Rock, Rock Beat, Bossa Nova, Mambo, Cha-Cha, Beguine, Rumba, March, Swing.
Size: 9-1/2" wide, 7" high, 12" deep. Weight 10-1/2 lb.
On the rear panel we have a jack for an external amplifier. There is also a jack for a foot-pedal control.
The speaker is on the top. Tempo switch to the left. To the right is the transformer. Careful with this if you open your 330 up. There are high voltages here which can be lethal.
This is the underside of the machine. On the right we have the voice board. The left is the pattern board. I haven't opened it up but I understand that its completely made from diodes..... the famous diode matrix where we have a network of intersecting horizontal and vertical buses. All discrete logic. Nice !!!

Roland TR-66 Rhythm Arranger
Roland TR-66 Rhythm Arranger
The TR 66 came out in 1973. It's importance in the history of drum machines can't be understated as it marks the transition between the four drums of the TR series - (TR 33,55,77 & 330) and the ground breaking CR series (CR 68 & 78).
Though it still bears the name TR, standing for transistor rhythm, Roland moved from a solely percussion based pattern machine (with pre chosen sounds), to one where 2 patterns could be combined.. The top 16 patterns were (chosen with a dial ) a kick, snare and hi-hat. The bottom consisted of your standard percussion patterns: Waltz, Jazz Rock, Slow Rock, Cha-Cha, Bossa Nova, Rhumba, etc. that you could find on the earlier TR machines These are selected by the buttons along the bottom row.
I really like the snare & kicks from this drum. All the sounds are warm & analog.The sounds include kick, snare, hihat, conga, bongos, claves, maracas, cowbell, rim shot, and cymbal. The TR-66 has been used by Depeche Mode and on the "Cha-Cha" rhythm on Roxy Music's "Dance Away" (1979).
Sadly, there is no way to sync the Tr 66 without modification.
The "Arrange Switch" offered two extra variations to the standard (AUTO) setting giving 36 patterns in total.
By combining the "Rhythm Selector" & "Variation Selector" interesting mixed rhythm patterns can be produced. When adding the Tempo, Balance control & the arrange switch, lots of variation is possible. A great little machine. !!!!

Fenix I & III (and a Roland CR 78)
video:
The Fenix III sequencer has a very useful clock divider (left of photo). The Roland CR 78 needs a 48 pulse per measure clock to sync. The Fenix clock divider needed a bit of tweaking but worked.
Here is the unedited video:

Akbar's Tomb - Agra, India
Akbar is arguably the most famous ruler from India's past. He was India's Mughal Emperor from 1556 until his death in 1605. His grandson (Shah Jahan) is famous for building the Taj Mahal.
These are pictures from his tomb.
The ceilings are magnificent. The tomb is a masterpiece of Mughal architecture. It was built between 1605 & 1613. It is situated in 48 Ha (119 acres) of grounds in Sikandra, a suburb of Agra
During his rule he enlarged the Mughal Empire to include the whole of the Indian subcontinent north of the Godavari river.

This is not his main tomb. It's just an out house.
What I find facinating about the man is how he kept the empire together....... through diplomacy, and conciliation. He was Muslim by birth but tried to unite the many faiths in his diverse country.
He tried to bring about religious unity and tolerance. It's a ideal we still strive for today.
I wonder what he would make of today's situation?
Akbar had 36 wives and over 300 women in his harem, but the legend goes that he had 3 favourite wives... One Muslim, one Hindu and one Christian. Whether this story is true I'm not sure, but you can see the fusion of the three forms of architecture throughout his palaces. He even promoted a new religion called Din-e Ilahi where he tried to take the best parts of Islam, Hinduism, Christianity, Jainism and Zoroastrianism and merge these into one.
Akbar concluded that no single religion could claim the monopoly of truth.
These grills are carved from single blocks of stone.

TKB build (The Human comparator kit) - Build Part 2
TKB build (The Human comparator kit) - Build Part 2
***Click here for the Index of the TKB Build ***
I though that before I start building the Human Comparator's TKB kit it would be fun to see what a vintage TKB looks like. I just happen to have one.This was built by my friend Warren Burt in the late 70's / Early 80's.
And it still works.
The first TKBs also appeared in kit form.
Here are the build instructions care of Ken Stone:
http://www.serge.synth.net/documents/kit/tkb.html
The particular TKB was restored in 2013 by Andrew F of Non-Linear Circuits.
OK, now it's time to begin my own build of this Serge classic

TKB - Touch Keyboard Sequencer - Build Part 1
TKB Build - Part 1 - Pics of the kit
The Human Comparator Clone.
*** Click here for the TKB Build Index ***
I've been looking forward to building this so much.
I remember back in the day, the TKB was the Holy Grail of Serge.
I understand these first came out in 1977.
The TKB is a combined touch sensitive keyboard and 16 step analogue sequencer.
What's not to like.
Zthee's website where you can purchase this kit is here:

And the official build notes of the Human Comparator

Also, of interest are the original Serge build documents.

Thanks to Zthee (THC) for making this kit available.... all the way from Sweden.
.... a land famous for synths.
I love the Japanese theme.
We have 16 capacitive touch-sensitive keys
Let the building begin.

The Unpopulated Faceplate.
Of course you can use it as a normal 4-bank sequencer, but it can do so much more... You can program your own scales for example. There is also a four-stage vertical sequencer which can step through each of the four layers.... this allows for sequences up to 64 steps.
