The Entity Bass Drum is a complete and versatile synthesizer voice geared for designing a huge array of bass drum, percussive and synth sounds. Finally, a truly deep tool for creating analog bass drum, bass lines and other percussive effects is here!

The design consists of a high fidelity resonant filter, 2 stage slope generator (rise/fall) with independent slope shaping, a high fidelity VCA and discrete transistor saturation circuitry. Every parameter on the Entity Bass drum is voltage controllable.

By applying a trigger of any length and at least 2V amplitude, we excite the resonant filter to produce a percussive sine wave. The pitch control tunes the output with a range of 8Hz to around 2.2KHz. Both higher and lower levels are achievable using the FM input for modulation etc. The internal filter will track 3-4 octaves reliably and the tracking device is temperature compensated.

Very high fidelity design - no generic op amps used in signal path. Only discrete components and audiophile grade op amps. Signal path is completely isolated from euro power rails. Very low nominal noise. High headroom using hotter signal levels and will cut through any mix.

The slope generator (ENV) can be switched into the circuit via the 3 way switch below the FM LVL control. This control is a bipolar attenuator which affects the level of the slope generator and/or external modulator that affects the pitch of the output.
The 3 way switch selects FM, FM+ENV or just ENV as a mod source.

The rise/fall envelope is a two stage function generator. The controls provide slope timing from 1ms to about a minute. To the right of these controls is the shaping section where logarithmic, linear and exponential slope shapes are selected independently for the two envelope stages.
The envelope is designed to re-trigger at a set point. This allows for changing dynamics to occur to pitch and amplitude when the slope times are greater than the output transient time. For instance the sound can vary between any number of triggers that fire before the envelope set point is reached. Setting the slope time fast enough (below roughly 1 o'clock) provides for nominal operation. Settings will vary depending on trigger and ring decay timing.
The envelope can also be used exclusively or in a more complex patch via a direct +ENV output. Additionally, a novel DUCK output provides a means to control external VCAs - to work like slow compressors. DUCK is an inverted and positively offset version of the +ENV out. This keeps VCAs open when the envelope is off and effectively 'ducks' the VCA when the envelope fires. Of course, mod sources for these outputs are not limited to VCAs...

BODY is a subtle, yet novel control. This control simulates the tightness of a drum head. All the way tight, we get a softer and somewhat muted sound, to the right we achieve a more flabby sound. The middle region is the sweet spot for a nearly perfect resonant drum. BODY can have a greater effect depending on the other parameters and can be very useful for fine tuning the sound in a mix and designing original drum sounds.

RING controls the resonant decay time. Both short and plucky and an infinite ring are obtainable. The filter is tuned so that it will always resonate a little, even when RING control is all the way down.

Before the output section, we have the discrete transistor saturation. We like this because of the vintage low end distortion from overdriven class-A discrete amplifiers. This one is tuned a bit more aggressively and just a touch is necessary to add some bite. However, you can go over the top and get brutal if you so desire... ;-)
The saturator will overdrive the output stage for more of a hard clipping effect that can be tuned out by adjusting the output level control without sacrificing signal amplitude - its a hot signal by intention.

The OUTPUT section is a parallel signal processor design. The OUTPUT control blends the nominal output with a secondary input (or nothing) depending on the 2 way switch setting below the control and/or whether an external signal is patched into the AMP CV input. In 'AMP' mode, the OUTPUT control works like a volume control. If a signal is active on the AMP CV input, the control will blend between the nominal output and the CV control level. Similarly, in 'ENV' mode we get the same blending action using the internal envelope.
The result is a sort of parallel compression effect as the output and CV sources are blended together - or totally independent at the extremes.
By providing amplitude shaping as well as pitch, resonant decay, body etc. even more sound shaping possibilities are available.

The VCA can also be accessed directly via the A-MIX input. This allows you to use the output section as a standalone VCA (modulated via the envelope or not) or to mix other sounds with the Entity. Feedback patching is a possibility using a stackable or mult to feed the output into the A-MIX input. This produces a juicy distortion effect of a different flavor, you may like it.

The filter can be used independently or in combination with the nominal output via the F-MIX input. This input is used as an aux trigger input that is sensitive to pulse/trigger width. As the effect is less dramatic than the main trigger, dynamic rhythms are achievable using both inputs and creative triggering.
As an acid style processor, patch a VCO input the F-MIX input and use the controls to modulate and accent the signal for some convincing 303 style acid bass lines and beyond.

Additional features:

PING! button to demo sounds without a trigger source.

RGB LED for visual feedback of trigger, FM and output waveform

All parameters are CV controllable. Controls double as CV attenuators.

Real leather, soft and lightweight
Color: Brown, Color: Brown
This medium sized leather tote bag is well made, with tight stitching; heavy duty, gunmetal colored hardware; and a thick, dark gray fabric lining on the inside. There are 2 short, rounded handles that do not fold down, and a narrow, flat, detachable crossbody strap that can be adjusted in length. The style is simple and classic, with a hand-dyed brown finish that will go well with most outfits. It's versatile, being suitable for work or everyday use. It can carry a small laptop or tablet, along with other essential items. There are no outside pockets, but inside there are several. The central compartment is spacious, with 2 slip pockets on one side. There are also 2 zippered pockets, with a large open pocket separating them. The top of the bag has a full, metal zipper that seems good quality. This bag is very attractive as well as functional, and though the leather feels lightweight the bag seems durable. Its listed price is a little high for my budget, but a coupon offer currently makes it a good value. I was very surprised that there is no logo or branding of any kind visible on the outside of this bag, and only one name label stitched to a pocket on the inside. Many bags I see have prominent names, symbols, or initials on the outside, and sometimes all over the inside lining as well. The simplicity of this bag is a refreshing change as it lets the quality speak for itself. I like it!

Great bag
Color: Brown, Color: Brown
This is a wonderful leather bag. It can be carried by handles or worn crossbody. It fits my 13" MacBook Pro perfectly though it doesn't have any particular padding to protect a laptop. I have a couple of nitpicks though for a bag that costs $98. 1/It's a shame that the handles can't lay down or disappear in some way when not in use. They just look a little goofy when you wear the bag across your body. And 2/the stitching is a little weird. The exterior shows the stitching for the inside pocket and I don't know that it's necessary. All in all it's a good bag but if I could return it I would consider doing so because of the way the handles stick up when worn crossbody. I do think, ultimately that's a dealbreaker for me.

This Bag Is Unbelievable - Serious Business
Color: Brown, Color: Brown
I’m a self-admitted bag enthusiast, and this one genuinely surprised me. I wasn’t familiar with the brand, but the quality is immediately apparent. The leather is soft yet substantial, giving it a premium feel without seeming fragile or flimsy. The stitching is impeccable, and the front and back are cleanly designed with no unnecessary frills—just a timeless, well-constructed silhouette. It’s the kind of bag that people notice, whether you’re carrying it or someone sees it from across the room. The strap was neatly packaged inside, and everything arrived in perfect condition. I looked it over carefully and couldn’t find a single flaw. In my opinion, this is a near-perfect everyday bag and an impressive value for the quality. *** Photos are front of bag (same as back), side of bag & bottom of bag. As you can see the stitching, as well as everything else, is quite impressive. Love this bag!

Gorgeous Color!
Color: Coffee, Color: Coffee
I am very happy with the color of this purse the inside pockets and zipped pockets, a total of 4, allows for neat organization of all my items such as phone, cosmetics, sunglasses, tissues, perfume, mints and etc... I love the gun metal colored hardware. The zippers move smoothly. The crossbody strap is long enough for my 6' frame and sits right at my hip when I use the last buckle hole. All the stitching is complete and tight. Speaking of stitching, I removed a star because the inside pockets are sewn on and shows on the back of the purse. I don't like having to check if my purse is facing the right way. For the price of this purse the stitching should not be showing. The interior lining is a cloth-like fabric. The inside zipped pockets are full size and lay on top of each other. This is different from what I've seen in other purses. When the purse is full, the top pocket slightly covers the main compartment bottom from view. I will be sure to put something somewhat flat in that pocket to avoid this. There is no offensive odor from shipping. Because of the stitching issue, I cannot recommend to others without point this out.

Doctor Doctor-give me the news!!! This purse is…
Color: Black, Color: Black
Amazing!!! This is an updated review because the seller sent me a replacement. I use this bag for photography. It’s easy to reach into and set down as needed. There’s room for one body and two lenses and multiple accessories. I use a wrist grip and do street photography. I don’t like to carry my camera around my neck and draw attention. This bag is perfect for keeping my camera in between shots. The bags interior is super soft and the leather itself on the outside feels high-quality and is stitched very well. Being footed is an extra great quality so that I feel confident setting it down. The extra long strap is great, as a large bag like this needs to be worn as a crossbody for most people I upgraded to a wide strap for the weight of my camera system. I always update my reviews in a year. So I will come back and let you know how it’s holding up! (Old review) ***********Arrived with someone else’s complaint already prepared for me! What an entrance!! She was right, the tag and bag don’t match. It is the bag I ordered but…. VERY VERY DAMAGED!!! For this much money, where is the quality control? Someone else’s return, and multiple gauges throughout the leather of the bag? I uploaded about 5 different places where the leather is gauged-and then stopped photographing. Sadly, I think this is a good bag - a bit overpriced, and small, the zipper is iffy as well but clearly the bag isn’t a keeper in this condition. Shame on the seller.
