Korg Mini Pops 7

The Mini Pops 7 was Korg's (Keio's) flagship Mini Pops.
It was also manufactured under the names Univox SR-95 & The Contessa Mini Pops.
The year was 1966.
The Univox SR-95 is virtually identical to the MP7, except that the Rimshot is not present and the Beguine rhythm also sounds different.
This is the Jean-Michel Jarre OXYGENE machine.
If you are looking for the original OXYGENE grooves, you can not get them without the Minipops 7

There are a total of 20 rhythms. The 10 rhythm white keys are assigned twice via the two pole selector switch on the right.
The top rhythms are: Waltz, Samba,Mambo,Rumba,Tango, Bossanova, Rock 1, Rock 2,  March 2/4 & swing.
The lower rhythms are :JAZZ WALTZ, MERINGUE, CHA-CHA, BEGUINE, HABANERA, SLOW ROCK, ROCK2, ROCK4, MARCH6/8, LATIN SWING
The rhythms can be combined with each other to create new patterns. This is how Jean-Michel Jarre created the rhythm for Oxygene, Part II.

The MP7 is the only model that offers all the 15 different drum sounds.
These are produced using inductors.... making this little drum very difficult to clone.
 I think the tonal variety in this machine is very impressive.
The sounds are: Bass, Snare 1, Snare 2, Rimshot, High-Hat, Cymbal 1, Cymbal 2, Cowbell, Conga, Large Bongo, Small Bongo, Claves, Quijada, Guiro, Tambourine.


I especially like the three distinct sounds Quijada ,Tambourine and Guiro.
These give it loads of character.
You can also mix these sounds with their own faders. This is rare a feature.
 Roland's CR-78 has a similar mixer.

For stage use , the device can also be set up vertically - The bottom has a carrying handle which can be flipped open .

The underside of the MP 7

Sadly the outputs are limited to just high & low impedence. But there are plenty of mods on the internet that describe how to obtain outs for each voice.

Inside the machine there are also lots of trimmer resistors which allow tweaking of the individual drum sounds.

Rhythmus - this is a free VST plug in that was inspired by the MP7

32 Hundred Volts - a Homage to the Korg PS 3200

We love our Korgs, especially the PS series.



The drum used in this recording was a Korg Volca Beats.
Here is a video taken during the initial recording:



EMS Synthi 100 in Melbourne Australia


There is a useful Muffs post on this synth here:
https://www.muffwiggler.com/forum/viewtopic.php?t=132637&postdays=0&postorder=asc&start=25
There have been rumours of the Synthi 100 floating around for years in Melbourne.
Finally, its official. The Melbourne Conservatorium of Music (part of Melbourne University) has announced that it's almost restored.

I'm sadly in Sydney, but hopefully will be able to view this beast in the flesh.
It's great to know that there are still technicians living in this country who can restore such instruments. Well done Leslie Craythorn.

Acid Glitch

A Korg Volca Sample, Kaoss Pad mini & Roland TB 303.

The full (unedited) video can be seen here:

The Volca Sample is a beauty of a drum machine.
... esp for distorted & malfunctioning glitch music.

The Volca has the smallest of memories so its samples are severely bit-rate reduced.

Korg (Keio) MiniPops 1

This is a odd one to categorize as it has no official name.
She looks like a minipops 5 (MP5). It's shape indicates that it was meant to sit under an organ or piano.
The MP5 was manufactured in 1966 as was the MP 7

Prior to the Mini Pops, Korg or Keio as it was known then, were famous for their Donca Matics.
So maybe this this could be called the Keio - Doncamatic Minipops. ???
Or shall it just be named "The Unnumbered MiniPop".????


And to make matters more confusing the MiniPop numbering system was not cronological.
The MP 5 & 7 came out in 1966.
The MP3 was manufactured in 1967.



Anyway, I think it's safe to assume that this drum was the first in the line of MiniPops, and was produced
in 1966 or before.

Temp, Cymbal & Switch-Volume dials. The Cymbal dial sets the volume level of the cymbal .... so you can cancel this sound completely if you like.


I really like the preset buttons which look like fake toy piano keys.
We have 16 patterns:
Waltz, Samba, Cha-Cha, Mambo, Rumba, Beguine, Habanera, Tango, Blues, Rock-Beat, Bossanova, Rock-a-Ballard, Swing, Six Eight, Fox Trot & March-Polka.

And you can combine up to 3 patterns at the one time.... creating some crazy rhythms


 The bottom cover slides off to reveal the inner PCBs.


We have 3 separate PCBs. The top is for the power supply.
The second (lower) PCB is the pattern generator. Notice the diodes.
The 3rd & largest PCB holds the voice circuits.


Well what does it sound like. It sounds nothing like a real drum. It's distorted . That bass drum is malformed beyond recognition. The snare and toms ... are they really toms ??? OMG.....well everything is twisted & misshaped. In other words I love this drum.


What was probably considered a mistake my the manufacturer makes this one a real find.

I'm seriously tempted to mod this one. The pattern board is at the top. I love the layout of these Japanese boards. They are logical & well thought out. It should be very easy to bypass the pattern PCB and trigger the voices directly.


I'll sit on that thought for a while. This drum is uber rare. It is good to sometimes leave things in virgin condition.

Modding ??? would be nice but maybe if I found a second one ....

The Tower of Victory ("Vijay Stambha" in Hindi) - Chittorgarh Fort - Rahasthan - India

This tower which was built in 1449 is located in Chittorgarh fort in Rajasthan.
Google Map of Chittorgarh

Called the "Tower of Victory", it was built to commemorate the victory of king Rana Kumbha over the combined armies of Mewar and Gujarat in 1446. There are 9 stories. It's built of red sandstone & marble.
Though dedicated to the god Vishnu, it is adorned with statues of other Hindu gods.
It stands nearly 40 metres high.

Each story is adorned with beautiful sculptures of Hindu gods.


The 8th floor Terrace. The 9th floor is closed to tourists.



 
The interior staircase. There are around 157 narrow steps leading to the terrace.

Each of the nine stories have openings and balconies that overlook Chittorgarh Fort,




These designs are carved out of blocks of sandstone & marble.




 The lattice work is simply stunning.

If you wait patiently, a time will come when you are alone in this magical place.
It's like you are surrounded by jewels.

The "Tower of Victory" perpetuates the model established by the previous Jain Temple - the 13th century "Tower of Glory" that was built by a Jain merchant near the Mahariva temple.

Roland CompuRhythm CR-800 Drum Machine

This is a very very rare one.
It's a cross between the CR-68, a CR-78 and a floor speaker.

She has quite a beautiful wood veneer.

Roland produced a few upright drum machines:

1969
++ Rhythm Ace FR-20 (Floor type)
++ Rhythm Ace FR-30 (Floor type)
++ Rhythm Ace FR-60 (Floor type)
++ Ace Tone Rhythm Ace FR-70 (upright drum machine)
1972
++ TR-700 Rhythm
 1978
 ++ CR-800 - very rare - upright drum housed in a speaker cabinet.

This standing upright configuration was common with companies such as Korg (eg: DA20 DoncaMatic rhythm machine), 

I understand that the CR-800 came out in the same year (1978) of the CR-68 & CR-78
The Roland CompuRhythm CR-68

It's nice to see all three drums together...... showing the evolution that was taking place during this important period in machine drum development. 

The CR-68 set the foundation. Though not programmable it had the same sounds & rhythm patterns as the CR-800 & CR-78 that were to follow.
The next step, the CR-800 had the same sounds as the 68 and was also not programmable. However, notice the change in the layout of the face. It's a 78 WITHOUT THE PROGRAMMER.
The evolution was complete with the CR-78. The sounds are still the same, and the face plate of the CR-800 has had its final makeover with the addition of the Programmer.

One interesting though superficial difference between the CR-800 & the CR-78 (apart from the rhythm programmer) is with the position of the accent & volume controls.

On the CR-800, the ACCENT is the top left slider & the VOLUME is the small knob to the left of the
Tempo knob. In the CR-78, these are reversed.
On a practical level these minor variations don't make a scrap of difference.

It's interesting to reflect that these three drums all came out in the same year of 1978.


Like the CR-68, this is not programmable. Rather we have preset patterns:
Rock1,2,3,4
Disco 1,2
Waltz, Shuffle, Slow Rock, Swing, A-Foxtrot, B-Tango, Boogie, Enka, Bossa Nova, Samba,
A-Mambo, B-Cha Cha, A Begunie, B-Rhumba.

One question that I'd really like to have an answer to is why this drum is called the CR-800?
If it lies mid way between the CR68 & CR78 why not call it the CR-72.5 ???
Maybe, it was produced after the CR-78 and the designers decided to call it the CR-80 then added a zero to the end ??? Baffling !!!!

The only other Roland Drum with a built in speaker from this era (1973) is the TR-330
It's also unusual in that the drums before & after also only used two digits.

And one final possible reason could be that the designers tried to make a connection with the TR-808
which came out in 1980 or the CR-8000 that would follow in 1981.


The case reminds me of the early days of drum machines when they took centre stage in your living room or were used to accompany a live band. This was probably meant to stand next to your organ or piano.
Love the voice cancelling buttons ... Cymbal/High Hat, BD, Snare, Cow Bell/Claves.
I'm glad Roland kept this function in the CR-78



The Add voice sliders - from left -
CY, HH, Metalic Beat.
Tambourin
Guiro


The speaker itself sounds cool. gives it a low-fi quality that i like.
There is however a speaker jack:







There is no way to sync this drum with external gear.
The CR-800 is too rare to mod. I think this beauty should be left as she is.
